Suggesting a small "Usage Example" fix in a comment?

[sergzach]

Probably that's a not very convenient comment in the "Usage":

- uses: actions/checkout@v4
  with:
    # Repository name with owner. For example, actions/checkout
    # Default: ${{ github.repository }}
    repository: ''

Because actions/checkout looks ambiguous as an example of a repository. This is the reference to the current action, it seems better to place here another repository name.
