[PATCH qemu-web] _download/windows.md: Drop 32-bit Windows support

[Peter Maydell <peter.maydell@linaro.org>]

32-bit Windows is no longer a supported platform for QEMU, and both
MSYS2 and Stefan Weil have stopped building 32-bit packages of it.
Remove the no-longer-working i686 pacman rune, and state explicitly
that 32 bit Windows isn't supported.

Fix a grammar nit in the page while we're here.
