use TypedDict for return type of legacy detect()

[pinterior]

Problem to solve

when I write something like:

x = charset_normalizer.detect(...)["encoding"]

x is inferred as str | float | None instead of actual str | None.

Change

use custom TypedDict type as the return type of detect method if Python version >= 3.8.
(TypedDict is not available in Python 3.7)

OK. The idea behind this is useful.
There's a stunt we can put in place to avoid the Python 3.7 blocker. Look at my draft suggestion for more.

I suggest otherwise to use the main API wherever you can instead of this old one.

that makes sense. committed.

CI action "MypyC Tests (3.7, macos-latest) (pull_request)" failing due to actions/runner-images#9770
should I create separate PR to use 'macos-13' image for Python 3.7 instead of 'macos-latest'?

no need, I will reorganize the whole thing anyway.
