PR Title: Update Footer to Include Dynamic Copyright Year

Description:

This PR enhances the footer section of the website by adding the current copyright year, which is fetched dynamically. This ensures that the copyright year will always be up-to-date without requiring manual updates each year.

Changes:

1. Footer HTML: Updated the footer to include a placeholder for the copyright year.
2. JavaScript: Added a script to fetch the current year dynamically and insert it into the footer.
3. CSS: Ensured that the styling of the footer remains consistent with the new dynamic content.

Benefits:

• Automation: The copyright year updates automatically, reducing maintenance overhead.
• Accuracy: Ensures the displayed year is always current, improving the website's professionalism.

Testing:

• Verified that the current year is displayed correctly in various browsers.
• Checked that the footer styling remains consistent and unaffected by the changes.
