Add developer jokes section to README

[Copilot]

This PR adds a fun "Developer Jokes Corner" section to the README.md file, making the repository more engaging and entertaining for visitors.

What's Changed

Added a new section at the end of the README containing 5 programming-related jokes:

• 🐛 Why programmers prefer dark mode
• 💡 How many programmers it takes to change a light bulb
• 💸 Why a developer went broke
• 🍺 A programmer's favorite hangout place
• 👓 Why Java developers wear glasses

Details

The jokes are:

• Light-hearted and appropriate for a professional developer's personal website
• Formatted in a clean Q&A style with proper markdown
• Enhanced with relevant emojis for visual appeal
• Separated from the main content with a horizontal rule for clear distinction

No functional changes were made to the website itself - this only affects the README documentation.
