What this PR does

Source file mined: workshop/23-ab-experiments.md

Side quest extracted: The "Understand how the round-robin works" and "Analyse the results" sections — a focused internals primer on gh-aw variant assignment that can stand alone without blocking the primary A/B experiment path.

How learner routing was updated:

• The extracted sections in 23-ab-experiments.md are replaced with a short summary and an Optional Side Quest callout linking to the new file.
• The "Before You Start" jump-link in Step 23 was updated to point to the new side quest instead of an in-page anchor.
• workshop/README.md gains a new entry in the Optional Side Quests section noting it branches from Step 23.
