Formatter: Unnecessary parentheses around return type annotations

[MichaReiser]

Ruff adds unnecessary parentheses around return type annotations that are either:

• guaranteed to break like multiline strings
• Come with their own set of parentheses

def test() -> """test
""": pass

def test() -> [aaa, bbbb,]: pass

def test() -> lists(a, b,): pass

Ruff

def test() -> (
    """test
"""
):
    pass


def test() -> ([
    aaa,
    bbbb,
]):
    pass


def test() -> (
    lists(
        a,
        b,
    )
):
    pass

Black

def test() -> """test
""":
    pass


def test() -> [
    aaa,
    bbbb,
]:
    pass


def test() -> lists(
    a,
    b,
):
    pass

I know this is somewhat of an edge case, but any workaround (tweaks in settings) for this?

Off-topic: maybe issues from here could be moved to a new Formatter: Post Stable milestone for easier tracking.
