Support $text operator on collection that do not use encryption while the service is configured with it

[TheRusCompass]

When the crud service is configured to use CSFLE with MongoDB the $text operator is not usable on any collection, even the ones that don't require encryption.

$text operator is explicitly rejected by mongo: https://www.mongodb.com/docs/manual/reference/security-client-side-query-aggregation-support/#supported-query-operators

However I may have different collections, and using encryption on one shouldn't block me from using text search on another collection
