Subject: [PATCH] Only run tests on macOS 12 (#5369)

There's an https://github.com/flutter/flutter/issues/138238 with mac_toolchain that makes Xcode installs flakey and an https://github.com/flutter/flutter/issues/138246 that makes Xcode installs more frequent on macOS 13, which is causing presubmit tests to fall frequently. In the meantime, we'll only have tests run on macOS 12.
