Misleading CLI error message: 'The command "env" does not exist.'

Issue

I fat-fingered a command and got a slightly misleading error message:

$ poetry --version
Poetry (version 1.4.1)
$ poetry env lsit

The command "env" does not exist.

Did you mean one of these?
    env use
    env info
    env list
    env remove

Seems like the error message should say something along the lines "lsit" is not a valid subcommand for "env" rather than boldly claiming that the "env" command does not exist :wink: But the suggestions are good and relevant!

Thanks for poetry - it has dramatically improved our project organization and workflows at Utilidata.
