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.

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.

Currently these are incorrectly scoped as attribute access (see attached screenshots). MVP to reproduce is simply

class Foo[T]:
  pass
