fix(tabs): onChange is not called when keyboard changes active tab

[Barsnes]

Summary

resolves #4605

I seems like this is an issue for react.
We could just remove the trusted line, but this make sure it keep the same functionality as before, but calls onChange if the users keyboard changes the value.

I'm open to just removing the line, since we always want onChange to stay in sync with the actual active tab.

Would be surprised if it does, since this does not stop the change event from our web component

If this is the best course, sure? Less complexity is always good :)

What was the problem with the onClick being done programmatically before?
Did we have this check pre v1.12.0?
