Fix

This is a small patch to allow for the parent package to override the sdkVersions

CI is telling us where the error is coming from:

[        ] A problem occurred evaluating project ':rinf'.
[        ] > No signature of method: static java.lang.Math.max() is applicable for argument types: (null, null, Integer) values: [null, null, 31]
[        ]   Possible solutions: max(int, int), max(double, double), max(float, float), max(long, long), wait(), any()

I'll update the PR to make it work :)
