chore: fix preview deployments

[AdrianGonz97]

The issue was that the ref and repository was removed from the preview workflow in a previous PR. Adding it back should fix preview deployments

      - uses: actions/checkout@v4
        with:
          ref: ${{ github.event.pull_request.head.ref }}
          repository: ${{ github.event.pull_request.head.repo.full_name }}

Before submitting the PR, please make sure you do the following

• If your PR isn't addressing a small fix (like a typo), it references an issue where it is discussed ahead of time and assigned to you. In many cases, features are absent for a reason.
• Prefix your PR title with feat:, fix:, chore:, or docs:.
• This message body should clearly illustrate what problems it solves.
• Format & lint the code with pnpm format and pnpm lint
