Clarify license

Would it be possible to clearly state under which license those skills are made available? That would help users know if they can "safely" use those and contributors to understand under what license their contributions will be managed.

It seems the vercel-labs/agent-skills repository mentions their are MIT (https://github.com/vercel-labs/agent-skills?tab=readme-ov-file#license). Is it the same for this repository? Could you add a proper LICENSE file?

Thanks!
