Fix workshop instruction issues and surface CLI workshop on GitHub Pages

[brunoborges]

Summary

This PR fixes several issues found during a review of the workshop materials in the workshop/ directory, adds a new workshop-cli/ variant adapted for the GitHub Copilot CLI approach, and surfaces both workshops on the GitHub Pages web interface.

---

Part 1: Workshop Instruction Fixes (workshop/)

#	File	Issue	Fix
1	workshop/01-prerequisites.md	Broken relative URL for Java JDK download link	Updated to full https://learn.microsoft.com/java/openjdk/download URL
2	workshop/01-prerequisites.md	Link to non-existent configure-settings-intellij.md	Updated to point to Microsoft Learn
3	workshop/02-assess.md	Instruction references non-existent asset-manager directory	Updated to instruct users to open the repo root
4	workshop/05-containerize.md	Typo in filename: copiotmd	Fixed to copilotmd
5	workshop/04-health-endpoints.md	Image named with old formula terminology	Added create-skill.png and updated reference

Also includes review.md documenting all findings.

Part 2: New CLI Workshop (workshop-cli/)

Adds a new workshop-cli/ folder that mirrors the existing workshop/ structure but replaces all IDE-based instructions with the GitHub Copilot CLI approach.

File	Change
00-overview.md	Updated title, description and steps table for the CLI workflow
01-prerequisites.md	Replaced IDE/extension prereqs with Copilot CLI, Node.js 22+, npm 10+
02-assess.md	Replaced assessment UI step with launching Copilot CLI and running /mcp add app-modernization
03-upgrade.md	Replaced UI task button with natural language prompt: Upgrade this project to JDK 21 and Spring Boot 3.2
04-health-endpoints.md	Replaced custom skill creation UI with a natural language prompt; removed the IDE-only note
05-containerize.md	Replaced Tasks panel UI flow with a natural language prompt; updated closing section to reference CLI docs

The CLI workshop covers the same modernization goals (Java 8→21, Spring Boot 2→3, health endpoints, containerization) entirely from the terminal with no IDE required.

---

Part 3: GitHub Pages — Surface CLI Workshop (docs/)

Updates the GitHub Pages web interface to expose both workshop variants.

File	Change
docs/index.html	Added "🖥️ Start CLI Workshop" CTA button in the hero section; renamed the existing workshop section to "IDE Workshop (VS Code / IntelliJ)"; added a new "CLI Workshop (Terminal / No IDE)" section listing all 6 CLI steps
docs/step.html	Added support for a ?variant=cli URL parameter — when set, the step viewer loads content from workshop-cli/ instead of workshop/, shows "CLI Workshop Steps" in the sidebar, and preserves the variant across all navigation (sidebar links, footer nav, and keyboard arrows)

Done in commit 5dc99a6. The CLI workshop is now surfaced on the GitHub Pages web interface with two changes:

1. docs/index.html: Added a "🖥️ Start CLI Workshop" CTA button in the hero section and a new "CLI Workshop (Terminal / No IDE)" section listing all 6 CLI steps, alongside the renamed "IDE Workshop (VS Code / IntelliJ)" section.

2. docs/step.html: Added support for a ?variant=cli URL parameter — when set, the step viewer loads markdown from workshop-cli/ instead of workshop/, shows "CLI Workshop Steps" in the sidebar, and preserves the variant across all navigation (sidebar links, footer nav, and keyboard arrow keys).
