Use built-in token

[Aariq]

Thanks for making this project, I think we'll find it useful in our organization. FYI, you can use a built-in GitHub token in actions with secrets.GITHUB_TOKEN. If you do that, you can skip all the stuff checking for the token expiration and remove the setup step where you have to create a PAT and store it as a secret. Other than that, it was a breeze to set up!

Hey! Great that this is useful to you, thanks for the message!

I am sure I had a reason for moving to fine-grained personal access tokens at some point, but now I can't quite remember why. Maybe during setup I ran it a bit too often and I ran into the rate limit? Perhaps there is a setting in the config of this repo that needs a fine-grained PAT?

If you're not running into issues just using the built-in token then great!
