Fix `Git` button and the `hamburger` menu label

* The `hamburger` label is not showing properly in different browsers.
  Maybe that specific html unicode is not supported in all browsers. I
  used a trick to fix this issue using the pipe character `|` ;-)
  You could read about that here too:

* The `down-arrow` unicode also did not work as expected through some
  browsers. It was decided to remove this label totally. Maybe later
  we can adopt using `standard` unicode html characters that are
  `known` to be widely used across various browsers in different
  platforms.
