I am working with a Geoserver Docker Image from their main repo

Also when I go to the rest url, I don't see anything under rest url of the workspace either.

From the download page you can always get to the archived versions (on the right) if for some reason you don't want to use a supported version.

However for community modules we only build them for the current snapshot. They can always be found on the build server. So, I would recommend moving to the 2.22.0 and hoping that the snapshot build will work or compiling it yourself. Of course if it's working is vital to your business then you should seek commercial support to move it to supported.
