[5.0.x] Refs #35194 -- Adjusted a generated field test to work on Postgres
15.6+.
Postgres >= 12.18, 13.14, 14.11, 15.6, 16.2 changed the way the
immutability
of generated and default expressions is detected in
postgres/postgres@743ddaf.
The adjusted test semantic is presereved by switching from __icontains to
__contains as both make use of a `%` literal which requires proper
escaping.
Refs #35336.
Thanks bcail for the report.
Backport of 73b62a21265c4a417004d64d13a896469e2558f3 from main.
