Is your feature request related to a problem? Please describe:

We are using Amplify Hosting with a connected GitHub provider.

When using Amplify Hosting with GitHub Pull Request previews, and when AMPLIFY_DIFF_DEPLOY is enabled, deployments are skipped as expected if no changes are detected. However, the GitHub Amplify App still posts a preview URL in Pull Request comments. This URL leads to a 404 error (or the Amplify welcome page) because nothing was deployed.

Describe how you'd like this feature to work

Amplify PR Preview URL should be posted only if deployment happened.
