The Web installer and the mentioned production branch are missing

It seems to be that the [web-installer](https://github.com/LuckPerms/web-installer) and the `production` branch mentioned in the [docs](https://luckperms.net/wiki/Self-hosting-the-web-interfaces) is missing. If one wants to self host the web editor now, which branch should be used? Is there a branch that is considered stable to be used in production?
