Add details to WSL documentation

Where did you find the move command? all sources seem to point to the method export then import being the only possible method of moving the install.

I can't recall where I found it first, but it is also in the output of wsl --help:

 --manage <Distro> <Options...>
        Ändert distributionsspezifische Optionen.

        Optionen:
            --move <Location>
                Verschieben Sie die Distribution an einen neuen Speicherort.

In the source I can't remember it was also mentioned that the move command is relatively new. May also be that it is only available in distros installed from MS store, not in those installed via wsl --install <DISTRO>

well I would add fallback information describing the export import method just in case the move function isnt available. So you are covering all bases.

Eg something like "if this command isnt available you can also perform this operation to move the install"
