Confusing help text for --unregister and --terminate arguments

Is your feature request related to a problem? Please describe.
The shortened help text provided within wsl --help for the --unregister and --terminate arguments are confusing to many users and do not provide enough information to disambiguate between the 2 arguments, nor do they really simply describe what actions they perform. Instead, the current help text merely reiterates what the argument name is! This is inadequate and not helpful:

    --terminate, -t <Distro>
        Terminates the specified distribution.

    --unregister <Distro>
        Unregisters the distribution.

Describe the solution you'd like
Provide help text that does not simply repeat the argument name but instead provides a well crafted help sentence that describes the action that each argument performs. Some of this helpful text can be borrowed from the official docs here: https://docs.microsoft.com/en-us/windows/wsl/wsl-config#unregister-and-reinstall-a-distribution

Replacement Suggestion:

    --terminate, -t <Distro>
        Immediately terminates a specified running distribution.

    --unregister <Distro>
        Uninstalls the specified distribution and deletes all data, settings, software associated with it.
