fixes #3545

I opted to push it to our GCP bucket but if we want to host it in ghcr then I suppose we can. The only caveats to doing that:

1. To pull the helm chart you will have to helm install oci://ghcr.io/coder/helm/coder which looks weird imo.
2. ghcr.io has no concept of helm so the helm package is going to look like it points to a docker registry. Which kind of supports the point that ghcr.io is kind of a hack.
3. I can't find a way to point the package to this repo since it's not a docker image, npm pkg, etc nvm I think we could still do this one
