Fix TypeQL reference includes (#1009)

## Goal
Replaces any broken references to reflect the move from `/reference/typeql` to `/typeql-reference`

## Implementation
Also nukes a copy of the tql files, fixes up includes and the tests which were failing for distinct & require by updating the queries.

 When used in a Define query, the `value` keyword defines the value type of an attribute type. When the attribute type is later instantiated, its values must be of the specified value type. There are currently these value types in TypeDB:
 
-include::{page-version}@reference::typeql/values/index.adoc
+include::{page-version}@typeql-reference::values/index.adoc
