parso can't parse PEP 695: Type Parameter Syntax

[heavenshell]

Hi, first of all thank you for creating awesome library. I'm useing parso in my library.

Python3.12 has big change at grammer. https://docs.python.org/3/whatsnew/3.12.html#whatsnew312-pep695

parso does not support PEP 695: Type Parameter Syntax.

import parso

code = """def func[T](arg1: T, arg2: T) -> T:
    return arg1 + arg2"""

module = parso.parse(code, version='3.12')
expr = module.children[0]
print(expr) 
print(expr.get_code()) 

output

<PythonErrorNode: def func@1,0>
def func

This example is def, but classes may be similar.

It would be very helpful if you could support the new grammar. Thank you.
