Improve docs for vendor specific private tokens + github fine-grained tokens

[Dominic-Marcelino]

Describe the feature

I've been happy to see that you've added support for accessing private repos via Token.
In our organisation we use the new fine-graded tokens. Which permissions do we need to set in order to use giget?
Content + Metadata readonly doesn't seem to work (returns a 404 error).

Would be great to get some documentation

Thanks a lot! :)

Additional information

• Would you be willing to help implement this feature?

I tested this with full permissions and it seems that I'm getting the same issue regardless. I am using this via Nuxt though, so might have something to do with this... Works immediately when using the classic token.

Testet this another time and seems like the endpoint does not supports the new Fine-grained personal access tokens (PAT).

I think a solution could be to add a git-mode like tiged/tiged does

For GitHub with fine-ganed access tokens, you need Contents and Metadata repository permissions. With them as I've tested giget works. Additional docs added to https://github.com/unjs/giget?tab=readme-ov-file#providing-token-for-private-repositories

Re git support, it is not a priority but you can track it from #84
