fix(scroll): fix scrolling on smaller screens (MIN-311)

When window height is too small (around 610px) vertical scroll appears but scrolling is broken. Added overflow-y for navbar to avoid vertical overflow caused by navbar content. Additionally, a scroll has been added in available plugins so that the user can see all available plugins when the list exceeds the height of the drawer
