Add support for Quay.io and GHCR.io as registries

- Added support for Quay.io
- Added support for GHCR.io

To enable support for these container image registries the following needs to be added.

As `Actions secrets and variables` - `Secrets`
- `DOCKERHUB_TOKEN` and `DOCKERHUB_USERNAME`
- `QUAY_TOKEN` and `QUAY_USERNAME`

As `Actions secrets and variables` - `Variables` - `Repository Variables`
- `DOCKERHUB_REPO`
- `GHCR_REPO`
- `QUAY_REPO`

The `DOCKERHUB_REPO` currently configured in `Secrets` can be removed if wanted, probably best after this PR has been merged.

If one of the vars/secrets are not configured it will skip that specific registry!
