crc setup - Make error message for port 2222 already in use more explicit

[PirMei]

Is your enhancement related to a problem? Please describe

I tried setting up CRC on Windows (11 64-Bit) and am using wsl-vpnkit for my company's VPN which by default uses Port 2222 for gvproxy.
When setting up CRC, I only figured out that crc wasn't set up properly when trying to start it (with crc start), however I poked around, thinking this was an error with previous installations of crc, podman desktop or similiar.
The crc setup command only shows the following, kind of nondescript message:

INFO Checking SSH port availability
crc uses port 2222 to run SSH

before returning control to my shell.

Describe the solution you'd like

The message displayed could be of type "ERROR" and be more verbose about the port being already in use (which is already obvious in debug log level but should be obvious in an actual error).

Describe alternatives you've considered

I also tried searching in documentation for "2222" and didn't find anything, so this could also be documented more thoroughly
