Revert BED-4662 PR 767

[mvlipka]

Description

Revert #767
We discussed using a new predicate instead of in:, but the changes were already staged for release.
This is to revert the implementation of the in: predicate in favor of BED-4726

Motivation and Context

Avoiding API changes from going out so that we may further improve on it before releasing to the public

How Has This Been Tested?

I tested the in: predicate to ensure it returns an error as the predicate is no longer supported
I then tested the supported predicates for the ListSavedQueries endpoint to ensure they still worked

Screenshots (optional):

in: no longer working:

eq: description working as intended

neq: description returns nothing

neq: description returns data

eq: name returns data

neq: name returns data
