This change updates the Android Target API to 36 to satisfy the upcoming
annual Play Store Aug 31 requirement. It updates Keyman for Android to
use API level 36 by changing the compileSdk and targetSdkVersion
properties to 36.
Also update `compileSdkVersion` and some reformatting in `README.md`.

Fixes: #16279
Build-bot: release:android
Previously the builder scripts defined a readonly `VERSION` environment
variable for the Keyman version. That caused problems when another
(external) script tried to define a `VERSION` variable. We encountered
this problem when trying to move the TC build steps of a configuration
into a single script (#13399) when we tried to source `~/.nvm/nvm.sh`.
This change uses a Keyman specific prefix for the version variables and
renames `VERSION` → `KEYMAN_VERSION` etc. Unfortunately these variables
are used in a lot of places, so this turned out to be a bit of a yak
shave.
Test-bot: skip
#2640 fixed the FirstVoices OEM app from crashing on Android 5.0 devices.
This applies the same fix (updating to `androidx.appcompat:appcompat:1.2.0-alpha02`) for all the other Android apps.

* Frebase
