⬆️ Update typing-extensions to 4.11.0

[Viicos]

Changes

Apart from here:

open-forms/src/openforms/appointments/models.py

Lines 87 to 88 in 53a8c84

	def is_str_list(values: list[Any]) -> TypeGuard[list[str]]:
	return all(isinstance(value, str) for value in values)

It is safe to use TypeIs for the other cases.

(Separate PR as I'll need it for another one)
