Test for .venv symlink (#6597)

Browse source 
For various reasons, I have a preference for out of tree virtual
environments. Things just work if I symlink, but I don't know that this
is guaranteed, so I thought I'd add a test for it. It looks like there's
another code path that matters (`FoundInterpreter::discover ->
PythonEnvironment::from_root`) for the higher level commands, but
couldn't spot a good place to test that.
