Make producers to use SASL configuration if on config file

[esteban-serfe]

Is your feature request related to a problem? Please describe.
On the documentation for the producers section the docs indicates to use Kafka::publishOn( $topic ).

When the settings are configured with SASL in place (using config/kafka.php file), this function will not read that part and you have to manually setup the authentication manually using https://junges.dev/documentation/laravel-kafka/v1.13/advanced-usage/3-sasl-authentication

Describe the solution you'd like
I'd like to have the new producers to honor the configuration settings that are global
