async101 & async119 now respects transform-async-generator-decorators

[jakkdl]

fixes #315

I noticed the flag wasn't documented at all in usage.rst, so added it there.
I also think it should be enabled for ASYNC119?

The flag becomes somewhat weirdly named for ASYNC101 since it will also suppress errors in sync functions. Idk if it warrants a rename, or I should just mention it in the docs, or explicitly only make it have an effect on async funcs, or something else.

hrm, I kinda wanna make the test_changelog_and_version tests be part of pre-commit. I keep forgetting to check those before pushing

probably remove the changelog from the first of this and #317 to merge, so we do a single release?

wait, I just noticed we have

def update_version() -> None:
    # If we've added a new version to the changelog, update __version__ to match
    last_version = next(iter(get_releases()))
    if last_version != VERSION:
        INIT_FILE = ROOT_PATH / "flake8_async" / "__init__.py"
        subs = (f'__version__ = "{VERSION}"', f'__version__ = "{last_version}"')
        INIT_FILE.write_text(INIT_FILE.read_text().replace(*subs))

which means the test for checking changelog matching __version__ is kinda redundant (contributor docs also say you should increment __version__). It'd perhaps be safer to do assert last_version == VERSION, and if we want the convenience of replacing __version__ that should perhaps be done in the pre-commit hook.

Oh I can't even have FUTURE stuff in the changelog because tests must pass to merge. I'll def do some retooling of this at some point
