RNA Connection Screen: update styles

[keoshi]

Changes proposed in this Pull Request:

• Updates styles on all connection screens, with and without required plan.
• Updates the default Jetpack logo color to #069e08 (Color Studio 40).

A couple of notes for @sergeymitr and @fgiannar:

• I've removed some button-specific styles from this code but we should get merged https://github.com/Automattic/jetpack/pull/21496 first to make sure the styles cascade down.
• For the image on the right side of Connect Screen, it would be cool if we could apply it as background-image rather than an <img /> tag so the wrapper height is always defined by the content on the left side. However, that involves changing the components and I wasn't totally comfortable doing that.

This should no longer be needed, it is handled in other PRs. Closing.
