Integrate Keystatic to edit twenty.com content (#10709)

This PR introduces Keystatic to let us edit twenty.com's content with a
CMS. For now, we'll focus on creating release notes through Keystatic as
it uses quite simple Markdown. Other types of content will need some
refactoring to work with Keystatic.
