According to https://github.com/sarugaku/shellingham#notes-for-application-developers the env vars should always exists. But yes, testing it doesn't hurt.

If poetry is not run within a shell, like explained in #2115, shell detection fails.
shellingham itself explain how one can try to detect a default shell via environment variables. This PR implements the suggestion.
Fixes: #2115
