Add verbose flag to pytest
Add verbose flag to pytest

When running in CI sometimes an assert statement would fail when
comparing strings, and you don't get the whole
diff by default, so you can't actually see what's going on,
which is annoying.
See https://github.com/staticjinja/staticjinja/pull/153/checks?check_run_id=2824261687
Therefore just always run with the `-vv` flag, it's OK if it's a bit
more verbose, it's not that bad.
