feat(infra/k8s): Rewrite cgit URLs by routing them through nginx r/229
Configures nginx to rewrite all requests to cgit, except for those
retrieving static files, to `/depot/`.

In combination with the previous commits that apply patches to cgit
itself, this effectively means that the depot is rendered on the site
root.

This is pretty cool: It lets people do stuff like `git clone
https://git.tazj.in` and get the depot!
