Description

Most of the Realm SDK's support the Realm Query Language in a text-based way. However the current docs do not have a page dedicated to this.

The closest is  https://docs.mongodb.com/realm/node/query-engine

which is specifically for JavaScript, but that is also missing some details described here https://realm.io/docs/javascript/latest/#filtering . At least SORT/DISTINCT/LIMIT is missing and possibly more

It would be nice that:

1. We have a docs page dedicated to the Realm Query Language that all SDK's can reference.
2. That this page is exhaustive, especially when it comes to more complex query constructs.
