Right now we're not just using an obsolete / unsupported version (r22) we're using the 22.0 version of it while r22b is out.

But we should move to the latest stable release https://github.com/android/ndk/wiki#current-stable-release

Right now that is r24 / 24.0.8215888

This is useful as part of a general strategy to get everything updated so native M1 builds work as well...
