Adds description on how to configure roave/psr-container-doctrine

[arueckauer]

Description

This PR provides an example on how to use it with roave/psr-container-doctrine.

Motivation and context

Laminas users will most likely utilize roave/psr-container-doctrine to integrate doctrine in their projects. The existing Zend Framework configuration is not compatible with it. The added description uses the psr-container-doctrine full-config example.

How has this been tested?

Locally tested. Since it describes the configuration of a third-party library, no tests were added. This change does not affect existing features or behavior.
