chore: fix release reference commit workflow

[marandaneto]

💡 Motivation and Context

The release workflow successfully published 7.14.0, but failed when committing generated references. The first ghcommit-action creates the release commit remotely, leaving the local checkout on the previous SHA; the later references commit then fails its expected-head safety check.

This PR syncs the checkout to the release commit before continuing and adds the generated 7.14.0 references that the failed workflow did not commit. The workflow output is passed through an environment variable before use in the shell to satisfy the GitHub Actions shell-injection rule.

💚 How did you test it?

• Parsed .github/workflows/release.yml as YAML
• Ran uv run bin/docs generate-references
• Validated generated reference JSON with python3 -m json.tool
