[Mono.Android.Export] Fix DynamicDependency to JavaArray (dotnet#6105)

For awhile, we've been observing ILLink warnings:

	ILLink warning IL2036: Java.Interop.DynamicInvokeTypeInfo.ToNative(CodeExpression): Unresolved type 'Android.Runtime.JavaArray' in DynamicDependencyAttribute

The cause is a "typo" in commit 15269f6, which added the
`[DynamicDependency]` custom attributes to
`DynamicInvokeTypeInfo.ToNative()`: commit 15269f6 specified the
non-generic type `Android.Runtime.JavaArray`, which does not exist.

Fix the `[DynamicDependency]` custom attribute value to instead
mention ``Android.Runtime.JavaArray`1``, the type `JavaArray<T>`.
This should fix the IL2036 warning.
