Privacy Policy page design

[melchoyce]

Related to #43491 and #43473, this ticket addresses the design of the Privacy Policy page.

This design is a riff off of https://core.trac.wordpress.org/attachment/ticket/43435/edit-privacy-policy-page.png.

The draft has three main pieces:

• Plugin Policies:
  • This is a collapsible box that lives above the Editor.
  • The header is styled like a warning notice, to attract attention to the text. The header contains an explanation of what the box contains and what you're supposed to do with it.
  • Each plugin providing a privacy policy will have a blurb and a "copy" button.
  • Question: Should the copy button copy text to the editor (I'd relabel it to "add to page page" or something), or just to your clipboard?
  • Question: Should there be some way to collapse or hide individual plugin blurbs?
• Core Policies:
  • Core policies are automatically inserted into the page content.
  • Question: Do we see us making changes to this text between the first GDPR release, and when Gutenberg is released?
• Confirmation:
  • This is inspired by the "Are you sure, [Author]?" confirmation the wordpress.org/news posts have.
  • The point of this extra step is to encourage people to review their privacy policy before publishing it.
  • When you check the box, the Publish button goes from disabled to enabled.
  • Question: Is this overkill?

Please note that none of the UI copy is final.
