Query execution diagram needs to be updated.

The Query Execution diagram here:

https://docs.couchbase.com/server/current/learn/services-and-indexes/services/query-service.html#query-execution

needs to be updated.

Currently "Projection" is shown after (to the right of) "Sort" which is no longer true (hasn't been for several major versions), it takes place before.  (Nothing after "Sort" can happen in parallel.)   The last item should perhaps be "Stream".

Further the Index and Search services are linked to "Scan" and should also be linked to "Join".
