aarch64-msvc: remove CI hack for bad Windows SDK version

This removes hack which manually replaced windows sdk version, as it looks like useless now, as CI uses newer version: https://github.com/rust-lang-ci/rust/actions/runs/5596259246/jobs/10233070602#step:24:929
`C:\Program Files (x86)\Windows Kits\10\include\10.0.22621.0\ucrt\corecrt_io.h` (look at version)

related rust-lang/rust#88796

It's nice to have some way to assert bad version, but i don't see anything except checking env rust-lang/cc-rs#646
