f-string with internal same-quote expression

[quittle]

Verified with https://black.vercel.app/?version=main

Describe the bug

Black fails to parse format strings (f-strings) where an express

To Reproduce

Default black settings with either of these

f"{""}"

Error

cannot use --safe with this file; failed to parse source file AST: f-string: expecting '}' (, line 1)
This could be caused by running Black with an older Python version that does not support new syntax used in your source file.

f"{'"'}"

Error

Cannot parse: 1:5: f"{'"'}"

f'''{'''"""'''}'''

Error

Cannot parse: 1:8: EOF in multi-line string

Expected behavior

The code can be parsed successfully, just as Python 3.10, 3.11, and 3.12 can successfully evaluate the code.

Environment

• Black's version: main and 23.10.1
• OS and Python version: Python 3.10, 3.11, and 3.12 on Ubuntu 22.04.2 in WSL

Additional context

Using f"""{""}""" works fine so long as the triple quotes aren't present internally.

Thanks, duplicate of #3746

(And note that Python 3.11 and lower cannot evaluate this code)
