Set up Android NDK for Fabric / new versions of packages

[karlhorky]

Once we want to upgrade to Fabric and packages like Reanimated v3, it seems we will need to install the Android NDK:

Reanimated 3 on npm is now down to 1.3M from 24M as we no longer publish prebuilt Android binaries. Before, we had to publish 40 different builds of the library (for every CPU architectures, every supported RN version, and separate for Hermes and JSC).

The cost of this change is that the devs need to have Android NDK set up. It is very easy to install tho (https://developer.android.com/studio/projects/install-ndk) and is already a requirement for other packages, and necessary if you want to use Fabric.
