The error:

ERROR: /Users/runner/work/envoy/envoy/mobile/WORKSPACE:98:18: fetching android_sdk_repository rule //external:androidsdk: Android SDK api level 30 was requested but it is not installed in the Android SDK at /Users/runner/Library/Android/sdk. The api levels found were [34, 33, 32, 31]. Please choose an available api level or install api level 30 from the Android SDK Manager.

This PR is a workaround to install Android SDK 30 even though it's not used for building iOS apps, that's because mobile/WORKSPACE expects the Android SDK 30 to be available and GitHub Runner image no longer includes Android SDK 30. See actions/runner-images#8952. Passing --android in the ./ci/mac_ci_setup.sh will install the Android SDK 30.
