The recyclarr docker image no longer requires root.
- `PUID` and `PGID` environment variables are no longer used.
- `recyclarr.yml` is no longer created if it is missing.
Fixes#102
A new `edge` tag will be published for docker builds resulting from
relevant changes on `master`. This provides an opportunity for the
community to test Docker-specific changes prior to the next release of
Recyclarr itself.
The non-root user and group were still being created in the Dockerfile,
which means that if the PUID or PGID were modified, those changes would
not be processed.
This change completely removes the `adduser` / `addgroup` commands and
instead the user spec is passed directly to `su-exec`.
