Document permissions required for Github Access Token

It's not clear what permissions this token requires. Perhaps the README could include instructions on a) how to create the token and b) what permissions are required?

# Optional: Enable this if you want to have GitHub Deployments triggered
gitHubToken: ${{ secrets.GITHUB_TOKEN }}

Ok, I just discovered it's an automatically generated secret https://docs.github.com/en/actions/security-guides/automatic-token-authentication 🙌

Might be worth mentioning that in the docs, but probably more my lack of experience with actions.
