Remove top margin for print layout

What does this MR do?

Remove top margin for print layout:

1. Removes extra top margin introduced by with-performance-bar class (only when performance bar is enabled)
2. Removes top margin from content-wrapper

This will reduce top margin approx by 90px with performance bar and by 40px without one.

You can see "before" behavior if you try to print this issue page. Although without performance bar it less of an issue.
