What is the standard post-receive hook <project>.git/hooks/post-receive?

I accidently overwrote Gitlab’s standard post-receive hook when I added a custom-hook, so now my “custom-hook” is now the new global post-receive hook. Can someone post the Gitlab standard post-receive hook that comes with the omnibus installation. It is located under ~git/git-data/user/<project>.git/hooks/post-receive I wasn’t able to find it anywhere online surprisingly…
