Prior to this change, the (incorrect) assumption was that `threadContext.isSystemContext()` returned true when dealing with system indices. This was eventually revealed to be false (though there is a separate issue where we aren't emitting deprecation warnings when running locally, but that is a separate thing). To fix this, the `DotPrefixValidator` now correctly receives a `SystemIndices` instance and uses the `findMatchingDescriptor` and `findMatchingDataStreamDescriptor` methods to determine whether a system index is being referenced. When a matching descriptor is found, the warning emission is skipped.

So this test fails before the addition to DotPrefixValidator?

Hmm… I thought that it would, but it doesn't appear to work. So I can remove this test. I'm not sure how to test this right now other than manual testing. I'll do some more digging to see how best to test this.
