Update test_black.shhh_click test for click 8+ (#2993)

The 8.0.x series renamed its "die on LANG=C" function and the 8.1.x
series straight up deleted it.

Unfortunately this makes this test type check cleanly hard, so we'll
just lint with click 8.1+ (the pre-commit hook configuration was changed
mostly to just evict any now unsupported mypy environments)
