[tests] update BuildReleaseArm64SimpleDotNet.apkdesc

[jonathanpeppers]

Some combination of merging:

• 32cff43
• f61cd81

We missed an update to this file, as Mono.Android.dll's size
increased beyond the threshold:

stdErr: Error: apkdiff: File 'assemblies/Mono.Android.dll' has changed by 4,468 bytes (5.10 %). This exceeds the threshold of 5.00 %.
Error: apkdiff: Size regression occured, 1 check(s) failed.

This fixes the test, going to merge:
