Complete the design system with the missing things

[michalgren]

Short overview

Based on @qbart feedback it would be nice to add additional designs to our design system.

ToDo

• Add additional shades of secondary/primary colors
• Error state in inputs, currently we have error state with a hint below input BUT it needs a bit changes: Change font to Sofia Pro, prepare forms to handoff as we can see nobody knows about that hint below input.
• Empty checkbox (without label) doesn't have proper error state
• Problem with copying logo will probably be completed within that task Prepare Selleo press kit #94
• Prepare a example form with couple of inputs,checkbox etc. and different states
