feat(release): Replace release bot with GH app

[Jeffreyhung]

The getsentry-release is a GitHub bot account that is used in various automation, and the ${{ secrets.GH_RELEASE_PAT }} is a personal access token from that bot account. We are using a regular GitHub account as a bot while it should be a non-human account since there are no humans behind it. Hence, we are replacing it with a GitHub App.

Functionality wise, there will be no difference.
