CLI: More MSYS2 fixes (#8577)

* CLI: More MSYS2 fixes

Now I can fully setup and work with qmk_firmware on an MSYS2
installation without any errors or exceptions.

* Apply suggestions from code review

* Some improvements

* Remove unnecessary import

* Remove slow, unused code

Getting the version from GIT was slow on both Windows and Docker.
Until we find a better, faster way, this is removed.

* remove unused imports

* Implement @vomindoraan's suggestions

* refine how we pick the shell to use

* Apply @fauxpark's suggestions

fauxpark investigated the topic of shells in MSYS2 a bit and we come to the conclusion that the safest bet was to just use the user's shell.
Anything more just opens up more edge-cases than it solves.

* Use `platform_id` in doctor

This will bring it in line with the new code.
