chore: use the default github secret for changeset (#1754)

### What does it do?

Changesets github action has been failing with a 403 using the env var:
GITHUB_TOKEN: ${{ secrets.CHANGESETS_GITHUB_TOKEN }}

This PR changes the release yaml to use the repository default so the
github actions runner can create the commits, branches and pull requests
that it needs
