poetry show and poetry install should throw an error when used with an unknown group name

[pmav99]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

Issue

Specifying an unknown group name on poetry show and poetry install (and possibly other commands that handle dependency groups) results in no error whatsoever. E.g.

poetry show --without gibberish && echo OK
poetry show --with gibberish && echo OK

poetry install --without gibberish && echo OK
poetry install --with gibberish && echo OK

IMHV, unknown group names, at least most of the time, imply typos and should result in an error.

The same happens e.g. in the export plugin, but I will open a separate issue there.
