Improve Testing on Windows OS

**Description**

Airflow does not currently support Windows (although there is some ability to run on WSL2).
This not only applies to installing / running Airflow but also extends to developing Airflow itself.

**Use case / motivation**

I develop on Windows (corporate requirement) and would like to improve the ability to test Airflow more easily.
My goal isn't to get the full test environment working on Windows, but just take some small steps to get to a point where it is somewhat functional. Using WSL is not ideal for me specifically as I can't install it on my development machine.

There is a lot of discussion already here: https://github.com/apache/airflow/issues/10388
Basically, getting Airflow on Windows is a large undertaking. This feature will assist with a (very) small part of it :)
