[ES|QL][Docs] Current Docs State counter field is unsupported, but it is technically supported via casting #115693

Problem Description
In the ES|QL Docs for Unsupported types it mentions that the TSDS counter field is currently unsupported, however, this isn't technically true; #107877 added "support" for this type via explicit casting. It would be helpful to have the documentation indicate that there is a way to leverage "partially" supported fields.
