* fix: set password encryption default to scram-sha-256

According to the Postgres official documentation, md5 passwords is
deprecated in favor of scram-sha-256 encryption.

The change in this PR updates the default encryption to the new postgres
default.

Documentation link:  https://www.postgresql.org/docs/18/auth-password.html

>Warning: Support for MD5-encrypted passwords is deprecated and will be removed in a future release of PostgreSQL.
