Fixes #342: Update Footer to Display Dynamic Year in Nightwatch Website

[rahulptl165]

Fixes #342

Description:

This PR updates the footer of the Nightwatch.js website to dynamically display the current year. The current implementation has a static "© 2023" text, which gives the impression that the website is outdated. The new implementation ensures the year is automatically updated using EJS.

Changes Made:

• Updated the EJS template for the footer to dynamically render the current year using JavaScript's Date object.
• Code snippet added:

  <footer>
    <p>© <%= new Date().getFullYear() %> Nightwatch.js. All rights reserved.</p>
  </footer>
