Enhance documentation with more examples of with and load usage for efficient relationship handling #160
Description
The Cycle ORM documentation currently provides a few examples of using with and load for loading relationships, but these examples are limited and do not always cover all the possibilities of working with these methods. This can make it challenging for developers to understand and utilize Cycle ORM's functionality for data and relationship handling. Therefore, it is proposed to expand the documentation and add more diverse and realistic examples of using with and load.
