Remove STE term and websearch_to_match variants in JSON schema

These aren't actually needed since STE term plaintext queries will be
encrypted as the same payload as ORE queries and websearch_to_match
queries will be the same payload as match queries.

Also add missing query variant for EJSON path queries.
