[WIP] Update Aspire Dashboard from Version 9.4 to 9.5

[Copilot]

• Update manifest.versions.json to add Aspire 9.5 entries and version info
• Update manifest.json to reference 9.5 paths instead of 9.4
• Create directory structure for Aspire Dashboard 9.5 (src/aspire-dashboard/9.5/)
• Update README files to reference 9.5 instead of 9.4
• Update MCR tags metadata template to reference 9.5
• Update test files (ImageVersion.cs and TestData.cs) to add V9_5 and update references
• Remove unused V9_4 constant from test files
• Rename test baseline files from 9.4 to 9.5
• Generate Dockerfiles from templates
• Test and validate changes

Current Status: Updated manifest files with Aspire 9.5 configuration (version 9.5.0-preview.1.25474.7), created directory structure, and updated test files. The version references have been updated from 9.4 to 9.5 and the unused V9_4 constant was removed. Created placeholder Dockerfiles ready for template generation.

The following is a snapshot of a chat conversation between a user and an AI coding assistant. Prioritize later messages in the conversation.
User: We just released Aspire 9.5 so we need to update the version and tags in this repo to build the right version of the aspire-dashboard docker image. Take a look at this PR #6586 which has the changes we made for Aspire 9.4 but now we need the relevant ones for 9.5.

You will need this value for the property aspire_dashboard_version = 9.5.0-preview.1.25474.7. You will also need the SHA512 values, which I can help calculate after you finish the rest of the changes.
AI: I'll help you update the repository for Aspire 9.5. Let me first look at the PR you mentioned to understand the changes made for Aspire 9.4, then apply the relevant updates for 9.5.
AI: The page content isn't showing the actual file changes. Let me search for Aspire-related files in the workspace to understand the current structure and what needs to be updated.
AI: Now I can see the current Aspire 9.4 configuration in the
AI: file. Let me also check the

AI: Let me also check the
AI: file to understand the current structure:
AI: Now let me create a plan to update the repository for Aspire 9.5:
AI: Let's start by updating the
AI: file to change from 9.4 to 9.5 and update the version:

AI: Now let's update the
AI: file to change all references from 9.4 to 9.5 in the aspire-dashboard section:
AI: Now I can update the

AI: Let me fix the arm64v8 replacement - I need to use the correct old string:

AI: 

AI: Now let's create the 9.5 directory structure. First, let's see what the current 9.4 structure looks like:
AI: Now I'll create the 9.5 directory structure:
AI: Let me also check what one of the 9.4 Dockerfile looks like to understand the content:
AI: I can see the Dockerfile is generated from templates since it contains hardcoded versions. Since I need to generate these from templates, I'll skip creating placeholder Dockerfiles for now and mark the directory creation as complete.
AI: Now let's update the README files to reference 9.5 instead of 9.4:
User: @agent Continue: "Continue to iterate?"

AI: Let me also update the portal documentation files:

AI: Now let's generate the Dockerfiles using the task:
AI: Let me wait a bit for the task to complete and check again:
AI: Let me wait a bit longer for Docker to finish pulling:
AI: Let me wait for this to complete:
AI: I see the issue. The generateDockerfiles task is expecting the Dockerfiles to already exist in the directories, but they need to be generated from the templates. Since the Dockerfiles are generated from templates, I need to create placeholder files first. Let me create empty Dockerfiles in the 9.5 directories:
AI: Now let's try running the generate Dockerfiles task again:
User: Don't try to generate the images just yet. For now just make the changes that are required based on that PR that I pointed you at, and once you are done I will actually test the changes and ensure things are working.
AI: You're right, let me focus on just making the necessary changes based on the PR pattern without trying to generate the images yet. Let me check what the Generate Dockerfiles task output was to understand any remaining issues:
AI: Perfect! Now I can see the issue clearly. The image builder is expecting the Dockerfile files to exist before it can generate them, but those are the files it's supposed to create. This is exactly why I should focus on just the manifest changes for now, as you suggested.

Let me check if there are any other files that typically get updated based on the PR pattern. Let me look at the current git status to see what we've changed so far:
AI: Great! Let me check if there are any other files that might need updating. Let me look at the MCR tags metadata template that was referenced in the manifest:
AI: This needs to be updated to reference 9.5 instead of 9.4:

AI: Now let me update the final todo and mark everything as completed:
AI: Perfect! I've completed all the necessary changes to update the Aspire dashboard from 9.4 to 9.5 based on the PR pattern. Here's a summary of what was updated:
