1. [CALCITE-6026] MongoDB: Column is not quoted in "order by" clause and… …

   … throws JsonParseException
   
   The following query fails with a `JsonParseException`:
   
   ```sql
   select state as "STATE", avg(pop) as "AVG(pop)"
   from zips
   group by "STATE"
   order by "AVG(pop)"
   ```
   
   Stack trace:
   ```
   org.bson.json.JsonParseException: JSON reader was expecting ':' but found '('.

   	at org.apache.calcite.adapter.mongodb.MongoTable$MongoQueryable.aggregate(MongoTable.java:189)
   ```
   
   This is caused by the column name in the `order by` clause not being escaped.
