Add this hamburger to the navbar for all the pages not just one

[VijaySamant4368]

@ayush-t02 many other pages don't require it.
There are no nav-bar items in these pages:

• Licensing
• Privacy Policy
• Terms of Service
• Game
• FAQ
• Contributors

The only page that should include the hamburger and doesn't already is about page, which I will improve right now.
Also there is a hamburger menu in the home page, with a slight error, which I will resolve.

If I have missed something, please do tell me.

I made the working hamburger in the About page

[VijaySamant4368]

In home page, the wired behavior starts at 768px and and remains like that as we reduce the width. The webpage becomes scrollable, therefore the hamburger doesn't appear at first, but if we scroll left, we can see that the hamburger is at the far right of the nav-bar.

@ayush-t02 Can I get a level 3?
