Add Handling and Raising Exception Training for Backend Developer

[MaxenceGui]

Summary

Managing and raising exceptions is a crucial aspect of developing our backend application. By providing targeted training on how to use exceptions in Python, we can ensure that CFIA's backend developers enhance their knowledge and expertise in this area. This approach benefits both the organization and the developer by providing them with the necessary tools to ensure consistency in code across all CFIA backend applications, as well as an understanding of the conventions used in other Python projects.

Steps by steps details of the work to be done

1. Read the Real Python Tutorial on the subject
2. Take notes and build our documentation
3. Modify TRAINING.md file to add the documentation to the backend developer training
4. Find a Lint test to validate good usage of exceptions in the backend code

Acceptance criteria

• The documentation is clear and covers the essentials of exception.
• The documentation leads to a clear convention and usage of Python exceptions for backend developers at CFIA.
• The lint test checks that the convention is followed.
