[BUG] Reverse operators for <, <=, >, >= defined incorrectly

[sophia-bq]

The REVERSE_OPERATORS in DocumentDbRules are defined in a way that returns unexpected results.

Ex. For a column val [1, 2, 3] select val from int_table where 2 >= val should return [1, 2]
Currently, the driver reverses the operator >= to be '$lt' which is the same as select val from int_table where val < 2 which returns [1]
The correct reverse operator is '$lte' which should return [1, 2].

This should be a very quick fix, I made the change locally myself and it looks like this: Reverse Operator Change
