[`ruff`] Validate arguments before offering a fix (`RUF056`) (#18631)
## Summary

Fixes https://github.com/astral-sh/ruff/issues/18628 by avoiding a fix
if there are "unknown" arguments, including any keyword arguments and
more than the expected 2 positional arguments.

I'm a bit on the fence here because it also seems reasonable to avoid a
diagnostic at all. Especially in the final test case I added (`not
my_dict.get(default=False)`), the hint suggesting to remove
`default=False` seems pretty misleading. At the same time, I guess the
diagnostic at least calls attention to the call site, which could help
to fix the missing argument bug too.

As I commented on the issue, I double-checked that keyword arguments are
invalid as far back as Python 3.8, even though the positional-only
marker was only added to the
[docs](https://docs.python.org/3.11/library/stdtypes.html#dict.get) in
3.12 (link is to 3.11, showing its absence).

## Test Plan

New tests derived from the bug report

## Stabilization

This was planned to be stabilized in 0.12, and the bug is less severe
than some others, but if there's nobody opposed, I will plan **not to
stabilize** this one for now.
