Use Github PAT for git operations

[drewwells]

💡 Feature proposal

When provided an access_token, use it for all git operations in additions to github operations. This way a single PAT manages all operations related to copybara. This feature is somewhat described here utilizing github credentials google/copybara#101

Use-cases

I want to copy files from one private repo to another private repo. A github PAT is created with access to both repos, but I do not have a ssh private key for either repo.

Example

action would configure git credentials with the PAT. Copybara would then perform operations utilizing the github pat in the credentials helper.

This is a good suggestion, thank you. I am swamped with work and currently only prioritize bugs on my OSS repos. If you or someone else want to pick it up, I will be happy to review the PR.
