[Feature Request] Allow GitHub App Installation Token instead of user PAT Token

[jmeridth]

To ensure the GitHub action is not dependent on a single user's PAT Token, I'd like to add functionality to allow for a GitHub App Installation Token. This may require a switch from github3.py though. I wasn't seeing it as an option with github3.py (still looking). github3.py handles app authentication, will stick with the same lib 😄

a GitHub App Installation Token is an efficient way to unlock the maximum alotted API calls to avoid rate limiting and can be used by multiple members of your organization

PyGitHub is what I've used in the past.

Definitely in scope and users would benefit from getting the max number of allowable API calls especially for large organizations. Thanks for bringing up and volunteering!
