fix: explicitly pass NODE_AUTH_TOKEN in publish workflow

The npm publish has been failing since Dec 31 with "Access token
expired or revoked". The token wasn't being explicitly passed to
the changesets action. Also removes auto-merge of Version Packages
PRs since GITHUB_TOKEN pushes can't trigger subsequent workflows.
