What problem is this PR solving?

This PR adds npm provenance support to our release workflow. Provenance is a security feature that allows consumers of our packages to verify where they were built and published from, enhancing supply chain security. With this change, our published packages will include provenance attestations that link them back to our GitHub repository and CI process.
