Add developer jokes to README

[Copilot]

This PR adds a fun "Developer Jokes" section to the README.md file, featuring a collection of light-hearted programming and tech-related jokes.

Changes

• Added a new section titled "😄 Developer Jokes" to the README
• Included 5 classic developer jokes with emoji decorations
• Separated the jokes section from the main content with a horizontal rule for better visual organization

Jokes Added

The section includes popular programming humor such as:

• Why programmers prefer dark mode (bugs and light!)
• The classic hardware vs. software joke
• A C# and Java pun
• The legendary Foo Bar reference
• A clever cache/cash play on words

Impact

Since README.md is excluded from the Jekyll build process (as configured in _config.yml), these changes only affect the GitHub repository page and do not impact the actual website at adrianmato.com. The jokes add personality to the repository while maintaining a professional and welcoming tone.
