Client git commit in output of docker version does not exist in any repo

[adamkpickering]

I am running Rancher Desktop 1.8.1 on openSUSE Leap 15.3, installed via the rpm.

After selecting moby as the container engine and allowing Rancher Desktop to finish starting up, I run docker version. This produces the following output:

adam@DESKTOP-PJ3KQUA [~/.rd/bin]$ docker version

The relevant detail is the Git commit field for the client. Its value is 393499b.

The problem is that this commit is not present anywhere I look: not in docker/cli, not in rancher-sandbox/rancher-desktop-docker-cli, and not in rancher-sandbox/rancher-desktop. I think that this has to do with how rancher-sandbox/rancher-desktop-docker-cli builds docker, though to be fair I'm not sure. This issue is about sorting this out.
