Closes #42865

Overall makes sense, but we should document the fact that we also changed the component contract here to take in stateful services as props.

Even though you did this in a way that's backwards compatible for folks importing from ui/public, it still feels like something we should have in the shared dev docs issue so people know that it isn't simply a matter of changing their imports.

I think it's low enough risk and effort to update the old import paths and delete src/legacy/ui/public/saved_objects/components/saved_object_save_modal.tsx but that can be done in a separate PR.
