Description We want to follow the best practices and achieve a higher code quality by using automatic tools (Husky, Prettier, ESLint and Staged-Lint). This PR contains both the setup of the tools and the fix of most existing code quality issues.

The goal to achieve is to remove all the custom rules existing in the .eslintrc.json file and pass with no errors and no warnings.
