Add new error messages for detecting lost connections (#47398)

Ever since I moved from AWS Aurora to using AWS RDS Proxy, which
(similar to pgbouncer) is essential to not overload the primary database
with connection, I sporadically see these messages. This affects
scheduled tasks, worker, HTTP requests; it's across the whole board.

This happened across different PHP versions (7.4, 8.2) and different
docker base OS images, as well as different Laravel version (8.x, 10.x).
