Bump CtsNetTestCasesLatestSdk to target SDK 30.

This is not necessary for the tests to be able to use APIs
introduced in R because they can already access hidden APIs.
But it is important to ensure that they are subject to whatever
new system behaviour is applied to SDK 30 apps.

Fix: 158839774
Test: treehugger
Test: atest CtsNetTestCasesLatestSdk has no new failures
