Tweak logo max width on the web editor
The logo's maximum width is now dependent on the viewport height
in addition to the page width. This prevents the "Start Godot editor"
button from overflowing the page on mobile devices (although the
"Clear persistent data" and "Web editor documentation" buttons will
still overflow for now).
