feat(release-notes): dry-run

[adrmachado-public]

Two fixes to actions/release-notes/action.yml:

• add explicit actions/setup-node@v6 step — the action previously assumed Node.js was already set up by a prior action in the same job, creating a fragile implicit dependency
• Replace awk/heredoc with TypeScript — the CHANGELOG parsing step used a multi-line awk expression writing to GITHUB_OUTPUT. Replaced with node dist/extract-release-notes.js (from the feat/git-utils PR)
• add dry-run boolean input to release-pipeline, and thread it to version-bump, npm-publish, and release-notes

tweaks:

• update the stale-branches action and pin to the latest commit SHA
• update validate-jira action to checkout the branch first before running the action. the ${{ github.action_path}} variable is not valid for shared workflows, only composite actions

All comments around optimizing/simplifying what we have.
