[ruby/rdoc] Improve <summary> CSS on sidebar

Browse source 
- Use a smaller font size for the toggle symbol. (Currently, it seems a little too large)
- Use the child combinator (`>`) to unify selectors.
- Use `margin-left` instead of whitespace within the `content` property.
- Use `::` instead of outdated `:` for the pseudo-element symbol.
  (See https://developer.mozilla.org/en-US/docs/Web/CSS/::before)
