fix(infra): create GitHub releases for partner package releases

[Mason Daugherty (mdrxy)]

• GitHub releases have not been created for partner package releases since fix(infra): block release on deepagents tests failure, bound min version for testing #34784 (Jan 16). PyPI publishes were unaffected.

#34784 added test-dependents to the publish job's dependency chain. test-dependents only runs for core/langchain releases, so it's skipped for everything else. publish handles this with if: ${{ !cancelled() && !failure() }}, but mark-release (which creates the GitHub release) doesn't have the same guard — so GitHub Actions skips it whenever test-dependents is skipped.

Missing GitHub releases
