This PR successfully implements important security hardening measures for the release workflow:

✅ Security Improvements:

• Adds default permissions: contents: read to restrict workflow permissions by default
• Pins GitHub Actions to specific commit hashes to prevent supply chain attacks
• Maintains clear version comments for traceability

✅ PR Title Compliance:
The title follows Conventional Commits format with the ci: prefix as required.

The changes are well-implemented and follow security best practices for GitHub Actions workflows. This hardening will help protect the release process from potential supply chain attacks.

This PR originally had the title and contents of what's now #565. release-plz seems to have chosen it to overwrite with the release PR because the source branch name happened to start with release-plz and be in the same repo. This will be merged once all other PRs tagged with the 7.3.0 milestone, including #565, are merged.
