Skip flaky prerelease add specs on Ruby 3.3 Windows due to SEGV

Ruby 3.3 on Windows has a native crash (SEGV in rb_ary_cmp during
Array#join) likely related to Object Shape optimization. The crash
corrupts version segments producing invalid requirements like
"~> false.12.3.pre" or "~> 2.12.3.pre".

This does not occur on Ruby 3.4+ where Object Shape implementation
was significantly improved.
