Update install CLI message for linux (#14616)

This PR updates the `cli: install` message for Linux. It initially threw
me off thinking that because `path_for_auxiliary_executable` is not
implemented for Linux it's failing and I thought it's a bug. Turns out
the CLI gets installed by the package manager and it's just named
something else.

I ended up only updating the message so it's more clear. If you don't
like the message, let me know :)

The old message:

The new message:
