SyntaxError after bad fix in f-string from Q000 flake8 bad-quotes-inline-string #10761
Description
Using ruff 0.3.5: the fix for https://docs.astral.sh/ruff/rules/bad-quotes-inline-string/ results in a syntax error

SyntaxError: f-string: expecting '}'Notes:
- The "fixed" syntax is only valid in 3.12 because it supports arbitrarily nested fstrings
- I cannot reproduce this bad fix using ruff 0.1.6
