Remove leftover ElasticSearch references after moving ElasticSearch out of repo

[Copilot]

This PR cleans up leftover ElasticSearch references that remained in the repository after ElasticSearch components were moved out of the repo.

Changes Made

Package References Removed

• Aspire.Elastic.Clients.Elasticsearch from tests/Shared/RepoTesting/Directory.Packages.Helix.props
• Aspire.Hosting.Elasticsearch from tests/Shared/RepoTesting/Directory.Packages.Helix.props
• Testcontainers.Elasticsearch from tests/Directory.Packages.props
• Elastic.Clients.Elasticsearch from root Directory.Packages.props

Code Updates

• Removed ElasticsearchResource from src/Shared/Model/KnownResourceTypes.cs
• Updated test methods in tests/Aspire.Hosting.Tests/ResourceExtensionsTests.cs to use nginx containers instead of elasticsearch while maintaining the same test logic and coverage
• Updated documentation examples in src/Aspire.Hosting/ApplicationModel/ResourceExtensions.cs to use nginx instead of elasticsearch

Testing

• All builds pass successfully
• Test methods maintain the same functionality with nginx containers instead of elasticsearch
• No functional changes to the API or behavior, only removal of obsolete references

The changes are minimal and surgical, focusing only on removing the leftover ElasticSearch references while preserving all existing functionality.

Fixes #9109.

@copilot please resolve merge conflict with main

@copilot please resolve merge conflict with main

Merge conflict resolved in 346a721. The main branch removed the entire s_builtInResources feature from KnownResourceTypes.cs, so I accepted the main branch version since removing "ElasticsearchResource" is no longer needed.
