The style of the "Button" block of Gutenberg needs to be aligned with the P4 styleguide / Primary Call to Action button (fonts / style / size / ALL rollover states - active / passive / rollover / click) >> https://planet4.greenpeace.org/styleguide/section-components.html  

Please only allow "Squared" style (see snapshot). 

Eg: https://k8s.p4.greenpeace.org/gutenberg/story/23962/test-fonts-on-text-blocks/

Please make sure also MENA (left-to-right) is aligned

Tasks

• Hide "Default" and "Outline" styles for button, and leave only the "Squared" option
• Adjust colour palette according to P4 style
