sorry for the unprofessional commit message, I have been working on this effectively non-stop since the previous commit, and have been fighting docker networking being inconsistent as well as filepermisson issues,
end me
Removed the rootless dockerfile as upon further investigation into how a `rootless` container works, the entrypoint that has been written fully accomodates that
to reflect this the compose file has had the rootless config removed from it as it is no longer needed to test a seperate container image,
added a debug echo function `decho` to the entrypoint, when `DEBUG=true` it will print "[entrypoint] message content"
added a 10 second wait to the entrypoint to allow other services such as docker-in-docker and forgejo to finish launching before the runner is launched, this is bypassable by `SKIP_WAIT=true`
applied several modifications requested by viceice,
