`redundant-expr` is annoying when using `assert_never`

[DetachHead]

from __future__ import annotations

from typing import Literal, assert_never

foo: 1 | 2

if foo == 1:
    ...
elif foo == 2: # error: redundant-expr
    ...
else:
    assert_never(foo)

a possible solution is to just not report redundant-expr errors if there's an else statement, because you would otherwise get an unreachable error anyway if you aren't using assert_never
