[Fix error]Unpacking an empty dict with PIE804

[Blumenkind111]

Hi all,

The following code seems to be unformattable by ruff with Rule PIE804

def test_function(*args, **kwargs):
pass

test_function(
arg1=1016,
arg2=25.4,
**{},
)

The error is: error: Fix introduced a syntax error. Reverting all changes.

I could break it down to this setting: ruff check testfile.py --select=PIE804 --fix

version is ruff 0.1.7

It's quite obvious, that ruff fails to unpack the empty dict into keyword-arguments, but when reformatting an old codebase it would be nice, if this (admittedly quite sketchy piece of code) would not crash the fix for the complete file.

Thanks for filing!

(The issue is the trailing comma.)
