Fixes: #10509
Changes: dotnet/java-interop@19be370...ef82a07

Update an existing test for #10509.

There is still a warning to fix in dotnet/java.interop:

MainActivity.cs(24,2): warning CA1416: This call site is reachable on: 'Android' 21.0 and later. 'ListView.Adapter.set' is unsupported on: 'android' 15.0 and later. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1416)

Let me see if the new test works in .NET 10, where I reverted changes.
