[BRANDING] parse FORGEJO__* in the container environment

Add the FORGEJO__ prefix as equivalent to GITEA__ when interpreted by
environment-to-ini. It is used when running the Forgejo container like
so:

  docker run --name forgejo -e FORGEJO__security__INSTALL_LOCK=true \
             -d codeberg.org/forgejo/forgejo:1.18
