Add comprehensive git commands with descriptions to README

[Copilot]

This PR addresses the issue by transforming the README from a simple placeholder into a comprehensive git command reference guide.

Changes Made

The README.md file has been enhanced with a complete catalog of git commands organized into logical categories for easy navigation. Each command includes:

• Command syntax with proper formatting
• Clear, concise descriptions explaining what the command does
• Practical context for when to use each command

Structure

The guide is organized into the following sections:

1. Configuration - Setting up git with user details and preferences
2. Creating Repositories - Initializing and cloning repositories
3. Basic Commands - Core git operations (add, commit, status, diff, etc.)
4. Branching and Merging - Managing branches and combining code
5. Remote Repositories - Working with remote servers (fetch, pull, push)
6. Inspection and Comparison - Viewing history and changes (log, show, blame)
7. Undoing Changes - Reverting, resetting, and restoring files
8. Stashing - Temporarily saving work in progress
9. Tags - Marking important commits
10. Advanced Commands - Cherry-pick, reflog, bisect, and more

Additional Features

• Table of Contents with anchor links for quick navigation
• Quick Reference Guide with common workflow patterns
• Tips and Best Practices section for git users

The guide now covers over 70 git commands, making it a valuable resource for both beginners learning git basics and experienced developers looking for a quick reference.
