Support argocd.argoproj.io/manifest-generate-paths

[gozer]

ArgoCD already has an annotation argocd.argoproj.io/manifest-generate-paths. similar to argocd-diff-preview/watch-pattern

It would be very handy if argocd-diff-preview supported using it as well as the existing argocd-diff-preview/watch-pattern for detecting changes in monorepos

Hi @gozer,

Yes, you’re absolutely right! This feature has been requested in other forums too, and it's a good point.

Supporting manifest-generate-paths is a bit more complex than the current watch-pattern. This approach would require parsing each source's path and appending the manifest-generate-paths dynamically — but it’s definitely feasible!

If anyone is interested in giving it a shot, I believe it could be implemented by modifying this function. I'll plan to work on this myself eventually, but contributions are always welcome!
