GHA/windows: apply MSYS2 runtime downgrades to v3.5.x, leave v3.6.x as-is

windows-runners 20250420.1.0 come with msys2-runtime 3.6.x. It has
the perf regression issue fixed, so stop downgrading it.

This makes CI jobs settle on this version when supplied by
the runner image or the msys2/setup-msys2 action:
MINGW64_NT-10.0-20348 fv-az980-636 3.6.1-0cfedd4f.x86_64 2025-04-12 01:44 UTC x86_64 Msys

With 3.6.1, we've seen issues launching `perl.exe` before this patch:
