Miscellaneous improvements to the typing docs (#105529) 
Mostly, these are changes so that we use shorter sentences and shorter paragraphs. In particular, I've tried to make the first sentence introducing each object in the typing API short and declarative.

gh-103763: Implement PEP 695 (#103764) 
This implements PEP 695, Type Parameter Syntax. It adds support for:

- Generic functions (def func[T](): ...)
- Generic classes (class X[T](): ...)
- Type aliases (type X = ...)
- New scoping when the new syntax is used within a class body
- Compiler and interpreter changes to support the new syntax and scoping rules

Improve assert_type phrasing (#104081) 
I'd like to make the fact that this does nothing at runtime
really obvious, since I suspect this is unintuitive for users who are
unfamiliar with static type checking.

I thought of this because of
https://discuss.python.org/t/add-arg-check-type-to-types/26384
wherein I'm skeptical that the user really did want `assert_type`.

T = TypeVar("T")
P = ParamSpec("P")

class X(Generic[P]):
    f: Callable[P, int]

Y = X[[int, T]]
Z = Y[str]
