Add a rating/review system for napari plugins

[pamitabh]

Hello everyone, I'm new here and excited to join the community!

I've noticed that while browsing plugins, I often rely on the number of downloads as an indicator of quality or functionality. However, I've encountered several plugins that don't function properly and sometimes even crash napari itself. Implementing a rating system for plugins could greatly enhance the user experience by providing more confidence to those looking to integrate new functionalities into their workflow.

I would love to hear your thoughts on this idea and if there have been any discussions or plans around introducing such a feature to napari-hub.
