Please add a note that restarting Postgres is required after setting the WAL level to logical

The doc page currently says

> **Step 1. Prepare the source database**
>
> Ensure that the PostgreSQL database is configured for replication. Enable logical replication by setting `wal_level` to `logical` in `postgresql.conf` or in the SQL shell. For example:
>
> `ALTER SYSTEM SET wal_level = 'logical';`

It is important to note that the above setting will not take effect until the Postgres instance is restarted.
