[skill-activity] Add active-learning quiz to environment reference side quest

[github-actions]

What changed

workshop/side-quest-01-02-environment-reference.md scored lowest (4.93/10) in the curriculum quality evaluation, flagged for active_learning (2.1) — a long glossary/reference page (1,433 words, 9 screenshots) with almost no hands-on interaction.

This PR:

• Adds a 6-item match-the-tool-to-its-role self-check quiz right after the glossary table, using the same <details><summary>Reveal answer</summary> pattern already established in 05-agentic-workflows-intro.md (Activity 2).
• Consolidates the nine per-tool screenshot subsections into five, pairing closely related tools (Codespaces/VS Code, gh/gh-aw, Copilot CLI/app, Claude/Codex) and trimming their captions to a single sentence each, cutting passive prose while keeping every image and fact.
• Adds a checkpoint item confirming the learner completed the new quiz.

Why this helps

This was the lowest-scoring workshop page in the latest curriculum quality run. It is an optional reference page, so the fix keeps its role intact (still readable any time, no terminal required) while giving learners an active retrieval task before they move on, per Mayer's active-processing principle and Sweller's Cognitive Load Theory cited in the evaluator's findings.

Workflow impact

No navigation, file names, or links changed — workshop/README.md and workshop/00-welcome.md do not need updates for this change.
