Add notification about the container registry on renaming project path

What does this MR do and why?

This MR adds an additional note regarding renaming the project path and the container registry.

We put this feature behind the feature flag renaming_project_with_tags as the ability to rename a project path with tags is gated behind that flag.

This MR is a prerequisite to rollout.
