Add strict type to test module

Hey Rajeshreeputra That's fantastic ! Successfully applied and tested the merge request #4 with strict types enabled is a significant step forward. Embracing strict types in Drupal not only aligns our codebase with modern PHP standards but also sets the stage for writing more resilient, maintainable, and efficient code.

By enforcing strict type checking, we're ensuring that our functions and methods operate with the correct types of data, reducing the chances of runtime errors and enhancing overall code reliability. It's a powerful tool for fostering a culture of quality and consistency within our development process.

Merged, release to follow shortly.
