CI: Pin third-party GitHub Actions to commit SHAs#5972
Merged

Conversation
Replaces every floating tag in our workflow and composite action files with an immutable 40-character commit SHA, keeping the original `# vX` comment so Dependabot can still propose version bumps. 186 occurrences across 25 workflows and 2 composite actions. Also widens the github-actions Dependabot entry to use the plural `directories` key with `/.github/actions/*` so composite actions under `.github/actions/<name>/action.yml` are kept up to date. Previously Dependabot only scanned `.github/workflows` and the repo-root `action.yml`, leaving our `python-setup` and `sample-validation-setup` composite actions unmaintained.

Changes:
- Pin third-party action
uses:references to 40-char commit SHAs across workflows and composite actions. - Widen Dependabot’s
github-actionsscan scope to include.github/actions/*composite actions.
