Fix Release build of RNTester

Summary:
Currently the release build of RNTester is broken
as it's loading the debug native libraries. I had to create
separate tasks for the two variants as we can't benefit
of automatic variant matching between project (as of now till
we use prefabs or find another approach).

Changelog:
[Internal] [Fixed] - Fix Release build of RNTester
