Collect all GenAI licenses for correct detection

We need to ensure that LLMs have a clear license. This is messy out there with a lot of new, weird, proprietary licenses.

There is something that would be super useful wrt. AI: find all these licenses!

The process would be:
- [ ] Collect the metadata files from all Hugging Face GenAi repos
- [ ] Scan GenAi metadata files with scancode
- [ ] Review GenAi metadata file scan results for correctness
- [ ] Create new licenses, and new license rules used @ HuggingFace

When cloning all the repos @ Hugging Face, these should shallow clones, without Git LFS and without xet large files, and possibly partial clone to focus only on a few files: model cards and licenses, and related metadata files. See for ideas:

Running ScanCode license detection on that and review the results to find all the funky new AI-licenses and notices may be best done in ScanCode.io for efficiency, but the licenses are ultimately created in ScanCode toolkit
