Has ContainsNone Operator been added

Description

I saw this post on GitHub: Implements `ContainsNone` Operator by avirlrma · Pull Request #4576 · weaviate/weaviate · GitHub

Which seems to suggest that the ContainsNone operator has been added, but I don’t find any documentation for it. Can you please clarify?

If it has not been added, is there a way to create a filter for an object property array to make sure that the results do NOT contain specific elements in the array?

Server Setup Information

I am running on WCS.

Any additional Information

For example, I have a text field which contains an array of the names of groups to which the object belongs.

What I want to do is to be able to add an exclusion filter.

I want to be able to say that if the object contains: Labor Private Group, Apple Private Group, Amazon Private Group or Netflix Private Group, it should NOT be returned.
