fix: Double default APK data size limit (#2060)

We keep hitting this because we have several packages in Chainguard OS
that are actually bigger than 4GB. Most of these are larger AI/ML
packages

This doubles the data size limit for APKs from 4GB to 8GB. 8GB is a
perfectly reasonable limit as the second largest APK in Chainguard OS is
7600276722 bytes (the first is... an outlier). There are plenty of other
packages that approach this limit as well
