Improve the error message for “multicommands” commands (#9510)

Browse source 
* Factor out the default `MultiCommand` behavior

All the `MultiCommand`s had (nearly) the same behavior when called
without a subcommand.
Factor out this behavior into the `NixMultiCommand` class.

* Display the list of available subcommands when none is specified

Whenever a user runs a command that excepts a subcommand, add the list
of available subcommands to the error message.

* Print the multi-command lists as Markdown lists

This takes more screen real estate, but is also much more readable than
a comma-separated list
