This reverts commit a7b25cece14dec12118cb63e05a0f2cb4b9cf36e.
The Crashlytics symbols uploder complains a lot - That it is

The Android Support Library is not androidx
https://developer.android.com/jetpack/androidx
This also required me to update each of the dependencies, as the
androidx migrated has resulted in major version changes in most of the
libraries.
