Allow encrypted_ prefix to be marked as encrypted in SQL detections

[cfabianski]

detect_encrypted_ruby_class_properties is the verifier we use to mark a SQL detection as encrypted.

We could add this new processor here that would automatically flag the fields that are prefixed by encrypted_ as encrypted.

package bearer.db_encrypted

 import future.keywords

 default encrypted := false

 encrypted = true {
     startswith(lower(input.target.value.field_name),  "encrypted_")
 }

 verified_by := [
     {
         "detector": "db_encrypted",
     }
