Add an option to filter duplicated manifests

[gpailler]

I'm implementing a filter to detect duplicates and to exclude them from the search results. When this filter is enabled, only one manifest is displayed (based on name and version)

It's working quite well but I'm struggling with the name of the option. I'm currently using "Unique manifests" but I'm not convinced. @rashil2000 @rasa any thoughts?

I ended up with "Distinct manifests only" wording.

This new filter is deployed on https://scoop.sh/ 🚀

How about adding a prompt similar to Google's suggestion when omitting duplicated search results?

In order to show you the most relevant results, we have omitted some entries very similar to the 174 already displayed. If you like, you can repeat the search with the omitted results included.
