Docker Hub image automated builds broken

[mstenta]

I broke the automated builds on Docker Hub when I cleaned up after farmOS/farmOS#580 :-(

Opening this so we don't forget about it...

We have a choice here:

1. Try to set it up like it was before (or similar). I think this will require creating a new GitHub "machine user". Previously we had a farmOS-docker user which I deleted.

• Remove farmOS-docker GitHub user from "Linked Accounts" in farmOS organization settings.
  • Deactivate farmOS-docker GitHub user? I don't think this is used for anything else.

2. Build the images via GitHub Actions and push to Docker Hub, like we are now doing for farmOS.

Build the images via GitHub Actions and push to Docker Hub, like we are now doing for farmOS.

I'd rather go this route, if possible, for consistency and simplicity/security (no need to maintain another GitHub user, all controlled through the same shared GitHub secrets that the farmOS repo uses). It requires some development/testing though...

It also means we'd have to manually create/push the 2.0.0-beta2 tag I think...
