Improving "FA100 / future-rewritable-type-annotation" message

[Avasam]

The message for rule https://docs.astral.sh/ruff/rules/future-rewritable-type-annotation/ Missing from __future__ import annotations, but uses {name} is slightly confusing / misleading. It sounds like I need to use from __future__ import annotations when using typing.Union, when it actually means that adding from __future__ import annotations can lead to simplified /modernized syntax. But that's also not checked unless relevant pyupgrades rules are turned on.

I think the message could be tweaked a bit to reflect that. I also assume FA and UP rules will likely be grouped together after the rules categorization #1774

The same issue.
FA100 false positive detection

python 3.9
target-version = "py39"

from typing import Optional

from aiohttp import ClientSession

class Client:
    def __init__(self) -> None:
        self._session: Optional[ClientSession] = None

Optional is highlighted with

FA100 Missing `from __future__ import annotations`, but uses `typing.Optional`
