Add prettier to the project

[tigerabrodi]

This issue aims to integrate Prettier into the project to ensure consistent code formatting across files. Prettier is a widely-used code formatter that automatically formats code according to predefined rules, enhancing code readability and maintainability.

Tasks:

• Install Prettier as a development dependency.
• Configure Prettier to adhere to project-specific formatting rules.
• Set up pre-commit hooks to automatically format code using Prettier.
• Update CONTRIBUTING.md to include Prettier usage guidelines for contributors.
