[GitHub Actions] Fix GitHub release missing changelog

[mho22]

Motivation for the change, related issues

Follow-up on #3488

The Publish GitHub Release and Update CHANGELOG.md workflows both trigger on Release NPM packages completion, so they run in parallel. This means the GitHub release reads CHANGELOG.md before it's been updated, resulting in releases with no changelog.

Implementation details

Changed publish-github-release.yml to trigger on Update CHANGELOG.md completion instead of Release NPM packages completion. This ensures the workflow chain is sequential:

1. Release NPM packages completes
2. Update CHANGELOG.md triggers, generates and commits the changelog
3. Publish GitHub Release triggers, reads the now-updated CHANGELOG.md

Testing Instructions (or ideally a Blueprint)

1. Trigger the Release NPM packages workflow manually.
2. Wait for Update CHANGELOG.md to complete.
3. Verify Publish GitHub Release triggers after Update CHANGELOG.md not after Release NPM packages.
4. Confirm the GitHub release body contains the actual changelog entries instead of "No changelog entries for this release."

Note

Copilot was unable to run its full agentic suite in this review.

Adjusts the GitHub Release publishing workflow trigger so it runs after the changelog has been generated/committed, preventing releases with empty/missing changelog content.

Changes:

• Update publish-github-release.yml to trigger on Update CHANGELOG.md workflow completion (instead of Release NPM packages)
• Enforce a sequential workflow chain: release → changelog update → GitHub release publish

I should have been more careful about this :

"No changelog entries for this release." :

@brandonpayton Manually running the Update CHANGELOG.md action will trigger the Publish Github Release but if there's no new NPM release it will be skipped. But in a way, it can be interesting to run Update CHANGELOG.md manually and update the Github release with the next version if it doesn't exist yet.
