fix: trying to publish when not needed

[jjangga0214]

      - name: Create Release PR or Publish
        uses: changesets/action@v1
        id: changesets
        with:
          commit: 'chore: release'
          title: 'chore: release'
          version: pnpm changeset version
          publish: 'pnpm -r publish && changeset tag && git push --follow-tags'
          createGithubReleases: true
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

It executes publish when it should not.

Currently in my repo, as the printed messages suggest, there's no changeset and nothing new to release.
So it should not publish, but it tries running the command 'pnpm -r publish && changeset tag && git push --follow-tags' which I set as publish option.

According to the docs: https://github.com/changesets/changesets/blob/main/docs/automating-changesets.md#blocking
Basically you can add a step that run this command:

changeset status --since=main

This will exit with exit code 1 if there have been no new changesets since main.
