doc: Note that CREATE MATERIALIZED VIEW restricts search_path.

Since v17, CREATE MATERIALIZED VIEW has set search_path to
"pg_catalog, pg_temp" while running the query.  The docs for the
other commands that restrict search_path mention it, but the page
for CREATE MATERIALIZED VIEW does not.  Fix that.

Oversight in commit 4b74ebf726.
