Unexpected behavior in f-strings with nested quotes

[BertLindeman]

Bug report

Bug description:

This "program" prints run

print(f"{"run"}")

This syntax is invalid as the nested double quotes should conflict with the outer ones.
It is expected to raise a SyntaxError.

This program (the same, but just without the 'f', so no f-string)

print("{"run"}")

reports:

  File "/home/bert/py/pybricks/issue/issue_1954_fstring_problem_syntax_simple_OK.py", line 2
    print("{"run"}")
          ^^^^^^
SyntaxError: invalid syntax. Perhaps you forgot a comma?

CPython versions tested on:

3.10, 3.12

Operating systems tested on:

Linux

[JelleZijlstra]

This syntax was newly added in Python 3.12. See PEP-701.
