• I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.

Describe the bug

Sync Phases and Waves documentation provides detailed information on configuring sync-wave for resource ordering during sync operations.
However, it does not explicitly mention whether duplicating sync-wave values across multiple resources is allowed.
I believe explicitly clarifying this in the documentation would help new users understand and configure it correctly.

To Reproduce

Expected behavior

The documentation should explicitly mention that:

1. Resources can share the same sync-wave value.
2. Resources with the same wave are processed together, ordered by their kind and name.
