Subject: [PATCH] chore(release): fetch all refs to validate commit on `main`

Use `fetch-depth: 0` of checkout action to fetch all refs, as per this
https://github.com/actions/checkout?tab=readme-ov-file#Fetch-all-history-for-all-tags-and-branches

Finally, use `git rev-parse origin/main` since we don't have a local
`main` branch ref.
