[Feature/Idea]: Document fine-grained permissions necessary for access token

[Throne3d]

What would you like to see changed/added?

I'm using komac to submit an update to HWInfo64, but wanted to use GitHub's new fine-grained personal access tokens instead of granting broad access. It would be great to have an easy list of permissions necessary to use this tool!

After forking the winget-pkgs repo, and granting read/write access to contents and pull requests, the tool was able to create a branch but seems to fail when creating the pull request

What would you like to do with REALiX.HWiNFO 7.62?
[x] Pull request
[ ] Write to files
[ ] Quit
Failed to create pull request after 3 attempts.
Reason: {"message":"Resource not accessible by personal access token","documentation_url":"https://docs.github.com/rest/pulls/pulls#create-a-pull-request"}.

I'm new to the tool, so I'm not sure what the full list of permissions is that's necessary for each functionality, or what exactly is missing to ensure it can create the final pull request.
