Remove the --gh flag from release.sh

release.sh --gh ran `gh release create` against GitHub. This project
publishes releases to Forgejo, and CI does it automatically on a v* tag
push (.forgejo/workflows/android-apk.yml attaches the signed APK for
Obtainium). The flag could not do anything useful here, and having it in
the usage text implied a manual publish step that does not exist.

Drops the flag, its DO_RELEASE branch, and the usage/header references.
--push remains the only option.
