macOS CI machines have outdated Android build tools (30.0.3 instead of 36.1.0)

The macOS CI machines appear to have Android build tools version `30.0.3` installed. That's surprising because the setup script `macos/mac-android.sh` specifies version `36.1.0`. This causes builds using `rules_android` v0.7.1+ to fail, as they require build tools `35.0.0` or newer.

## Reproduction

Any project using `rules_android` >= 0.7.1 with `android_sdk_repository_extension` will fail on macOS CI.
