Mobile menu - wrong padding & dark mode switch

[HonzaTuron]

• On mobile, the dark mode switch in docs overlaps with the docs header
  

• On mobile, the docs menu items have inconsistent margins
  

• The favicon for Apify Docs is using the old logo colors

Let's remove it from the expanded left menu - it's always available in the navbar

well, it's in there for mobile version, where you don't see it in the navbar, so we cant just remove it.

FWIW, with resolutions with >=375 width it looks good, i guess most of the today's devices have at least that?

we can surely just hide it on smaller screens, its not that important feature. or move this via CSS a bit downwards

@jbartadev I don't think this falls on us, why would it? Thx
