`tests/ui/associated-consts/issue-93775.rs` seems to be flaky

I was modifying the compiler for unrelated changes on x86_64-pc-windows-msvc, and the tests/ui/associated-consts/issue-93775.rs ui test seemingly randomly failed, a rerun with nothing changed made the test pass, and now I can't reproduce it easily.

I don't have a good solution to this, having the test being flaky is not ideal, but neither is outright deleting this because this is a regression test for the original issue that segfaulted.
