[PATCH] docs/about: Update the support statement for Windows

[Thomas Huth <thuth@redhat.com>]

Our support statement for Windows currently talks about "Vista / Server
2008" - which is related to the API of Windows, and this is not easy
to understand for the non-technical users. It might also not be quite
true anymore, since we only compile-test QEMU with recent toolchains.

Thus I'm suggesting to change the support statement here to something
similar that we use on Linux: Only support the very latest major release,
with support for the previous major release being dropped after two years
of overlap.

And since we're nowadays also compile-testing QEMU with MSYS2 on Windows
itself, I think we could also mention this build environment here.
