This commit updates the NDK version to latest available at the
time.
The expectation from this change is to resolve issues with code
modernisation and to allow us to use C++ 17 features on Android.
This shouldn't affect devices supported as we're not changing the
API level.

When a single GitHub Action build fails, the other builds should not be
canceled, but instead should continue to build.
Since the matrix is setup on OS level, a failing build on one OS usually
doesn't mean it's broken for all OS.
