Plugins banner: show the WordPress.com logo and heading at their intended size

[claudiucelfilip]

Proposed changes

• The banner at the top of the Add New Plugin screen now shows the WordPress.com logo at 160px wide. Before, it rendered at its full image size, over 500px on wide screens.
• The banner heading is now 40px, with even line breaks, and sits slightly further below the logo to match the design.

No.

Testing instructions

• On a WoA dev site, install Jetpack Beta and switch WordPress.com Site Helper to this branch. (Switching it on a regular Atomic site fails because the site's mu-plugins folder is read-only.)
• Go to Plugins → Add New Plugin.
• The WordPress.com logo in the dark banner is 160px wide, and the heading "Unlock more with premium and free plugins" is 40px and wraps evenly.
• Below 782px wide, the heading drops to 24px as before.
