fix(all, android): purge jcenter() from android build

[mikehardy]

Description

Only remaining jcenter usage is in our tests app, not used by
library consumers, where we must retain it until react-native itself
is jcenter-free

Also bumped everything in the template to current and bumped kotlin in tests app to 1.4.32 from 1.4.31 but no one will notice or care ;-)

Test Plan

I ran yarn tests:build:test to make sure everything still built after. It still builds, unless you comment out the final jcenter line, then it fails on known problems (link above).
