Subject: [PATCH] CI(notebooks): tolerate upstream drift + add nbformat to
 api-introspect

First CI run on PR #5312 surfaced two issues:

1. static job: drift step found 463 files of drift (7359 / 9634 line
   delta) on unslothai/notebooks @ main. That is a real upstream
   backlog the notebooks-side maintainers need to address; this
   workflow's role is to surface the count, not auto-fix. Mark
   drift + convert as continue-on-error so the count surfaces in
   the PR check UI without blocking. Drop continue-on-error once
   the count returns to zero.

2. api-introspect job: pip install step did not include nbformat,
   so the convert subcommand crashed with ModuleNotFoundError on
   every notebook. Add nbformat + nbconvert to the install line
   (matching the static job's deps) and mark its convert step
   continue-on-error for the same upstream-tolerance reason.

Pre-existing failures on PR #5312 (Chat UI Tests Playwright timeout,
CodeQL job) are unrelated and out of scope for this commit.
