Bump typing-extensions and mypy for ParamSpec

[uranusjr]

I want to use them in some @task signature improvements. Mypy added this in 0.950, but let's just bump to latest since why not.

Changelog of typing-extensions is spotty before 4.0, but ParamSpec was introduced some time before that (likely some time in 2021), and it seems to be a reasonble minimum to bump to.

See PEP 612 for more about ParamSpec if you’re interested. But in short, it solves our problem when typing @task—the resulting task should accept the same arguments as the wrapped function inside, but when called should return an XComArg, instead of the wrapped function’s return value.

# This is a Callable[[int, str], str]
def foo(a: int, b: str) -> str:
    return b * a

# How can we type the wrapped task as Callable[[int, str] XComArg]?
# ParamSpec makes this possible.
@task
def foo(a: int, b: str) -> str:
    return b * a

Nice! Let's see how many errors it will produce to fix though :)

Oh no

[uranusjr]

Alright, the failures are fixed. I am not sure with a lot of the changes I made, so please lend an eye if you could.
