For some reason when exporting the android project it now adds

android.aapt2FromMavenOverride=/opt/unity/Editor/Data/PlaybackEngines/AndroidPlayer/SDK/build-tools/34.0.0/aapt2

to the gradle.properties. That path does not exist in the job that compiles the project.
It looks like we need to either

1. Fix the path: i.e. overwrite it in the .properties
2. Remove the line and add it to the local.properties instead
3. And/Or figure out why this is only an issue on 2022 and not 6
