QA: redact errors output during explain analyze (redact)

[rharding6373]

When a query fails during an explain analyze ... redact, we currently may include constants we would expect to be redacted in the error output.

In the following query and output using MOVR on cockroach demo:

EXPLAIN ANALYZE (PLAN, REDACT) INSERT INTO vehicle_location_histories (city, ride_id, timestamp, lat, long) VALUES ('amsterdam', 'cd032f56-cf1a-4800-8000-00000000066f', current_timestamp(), -101, 60)
 ERROR: insert on table "vehicle_location_histories" violates foreign key constraint "vehicle_location_histories_city_ride_id_fkey"
 SQLSTATE: 23503    
 DETAIL: Key (city, ride_id)=('amsterdam', 'cd032f56-cf1a-4800-8000-00000000066f') is not present in table "rides".
 CONSTRAINT: vehicle_location_histories_city_ride_id_fkey

We would expect constants like 'amsterdam', 'cd032f56-cf1a-4800-8000-00000000066f' to be redacted from the explain output, so should we expect them to be redacted from the error output as well?
