fixed navbar top gap

[yassine-safraoui]

In your docusaurus config you're setting the hideOnScroll of the Navbar to false so that the navbar is sticky, and apperently there is a bug in docusaurus that makes a 1px gap apear on top of the navbar in this situation on some zoom levels( like 125% in my case), so when the user scrolls the content behind the navbar could be seen through that gap, like you can see in this picture:

This behavior is well documented in this stackoverflow question: https://stackoverflow.com/questions/64729642/css-sticky-ignores-1px

The root of the problem is the combination of position sticky and top 0, the solution is to simply add a top of -1px to the navbar to compensate for the gap, it's the only thing I added as you can already see.
