Auto merge of #9646 - ehuss:windows-case-disable, r=alexcrichton

Temporarily disable windows env test.

This temporarily disables the `target_in_environment_contains_lower_case` test on Windows until https://github.com/rust-lang/rust/pull/85270 gets into nightly.  That PR changes it so that env vars are case-preserved on Windows.  My intent is that after that is in nightly, we can remove the windows-specific code in `Config`, and this test should work the same on all platforms.

Closes #9630
