Incorrect f-string parsing

[hauntsaninja]

Not the best string ever, but ruff doesn't handle it like Python

λ cat test.py
print(f"$N_{{img}}\in\{{0,1,2\}}$")
λ python test.py
$N_{img}\in\{0,1,2\}$
λ ruff check test.py --select F401
error: Failed to parse test.py:1:25: f-string: unterminated string

Nice, thanks -- re-opening on the parser as RustPython/Parser#88.
