PR Summary

• New Section: Open Repository in Browser
  We have added a fresh section in the documentation called "Open repository in browser". This provides instructions and the necessary code to facilitate the installation of the GitHub Command Line Interface (CLI). Once installed, users will be able to easily open their repositories directly in the browser.

• Script for .gitignore File Generation
  In an effort to simplify the initial setup of new projects, we've included a script that automatically generates a .gitignore file by using gitignore.io. This file is essential for defining what project files the Git version control system should ignore, thus preventing unnecessary files from being uploaded to the repository.
