cleanup UI link list

[slaren]

• Removed links that no longer work or that do not reference llama.cpp
• Removed the blurb in the few links that had it

When I originally added the list my idea was to explicitly mark those projects that do not use permissive licenses since those are the cases where you can potentially get into legal trouble. But subsequently license declarations were added for permissive projects anyways wo maybe it would make sense to remove the sentence prior to the list and just list the license for each project?

[slaren]

Yes, I will try to add the missing licenses and remove the sentence.

Looking at the list I'm noticing that the names for Github repositories are also inconsistent: for some it's <Github user>/<repository name> and for some it's just <repository name>. I don't have a preference but while we're at it I think it would make sense to use a consistent notation.

[slaren]

Most of these were added by the project authors themselves, so I think it is ok to leave it the way they prefer it.

[JohannesGaessler]

That's also fine I guess.

Btw I'm also thinking about these ideas:

• Maybe move supported models, binding, UI, etc into a page called showcase.md, leaving "Usage" on top of the main README
• Maybe also remove downstream project that haven't been updated for a long time (i.e. check their last commit)

[slaren]

Agree, the lists are getting too big and they kind of detract from the more important information in the README. I will leave that for a different PR, though.

The UI list in particular could be listed as one of the methods to use llama.cpp.
