Description
Related to #229: when writing a generic class/function that uses type parameters, the syntax is incorrectly highlighted. This syntax was introduced in 3.12 via [PEP 695](https://peps.python.org/pep-0695/).
Currently these are incorrectly scoped as attribute access (see attached screenshots). MVP to reproduce is simply
```python
class Foo[T]:
pass
```

Research direction
Start with the PEP 695 examples and reproduce the issue using `class Foo[T]: pass` in a supported editor. Inspect the syntax-highlighting rules that assign attribute-access scopes to type-parameter syntax. Done means the PEP 695 forms receive appropriate scopes and the regression is covered by the project's existing tests, if available.
