Counter isn't documented

[liamjones]

How frequently does the bug occur?

Always

Description

While working through #6943 I've been referring to the docs quite a lot for all the types Realm supports. Counter doesn't seem to be documented currently: https://www.mongodb.com/docs/atlas/device-sdks/sdk/react-native/model-data/data-types/property-types/

Apolgies if this is reported on the wrong project, the PR template just says to mention @realm/devdocs but I couldn't find a doc repo in the realm organisation

For what it's worth, there's SDK level documentation for this: https://www.mongodb.com/docs/realm-sdks/js/latest/classes/Realm.Types.Counter.html
