refactoring swagger config (#213)

## PR Description
Hey team,

This pull request aims to improve the code structure and organization of
the app.js file in our GitHub repository. The main objective is to
enhance maintainability and readability by moving the Swagger
configuration code to a separate file called setupSwagger.js. By doing
this, we can achieve better separation of concerns and adhere to the
single responsibility principle.


## Changes Made
- Created a new file called setupSwagger.js in the appropriate
directory.
- Transferred the Swagger configuration code from app.js to
setupSwagger.js.
- Updated the app.js file to import the necessary functions or
configurations from setupSwagger.js.
- Verified that the application remains functional after the code
refactoring.


## Notes for Reviewers
Please review the changes made in this pull request carefully, paying
particular attention to the new setupSwagger.js file and the
modifications in app.js. Any feedback, suggestions, or improvements are
welcome

Best regards,
Louay HICHRI
