Plugin V2 Design

[victorb]

Current plugin is lacking a lot of features that would make the UX a lot better.

• Select which website in Instant Website to be connected to (dropdown with a list of websites)
• Login without copy/paste tokens (a button for triggering the login + show current logged in user)
• Select which account we're authenticated with (dropdown with list of currently logged in users)
• Properties panel for adding attributes to elements (we want to be able to add videos via URLs for example), should be able to be easily extended in the future as we add more attributes
• General settings for the current website (like starting page, description and so on), also easily extendable
• Loading states for when you change connected account/website and we need to reload resources from Instant Website

Existing features that should also be in V2:

• Create/update the website
• Link to Dashboard and Instant Website landing page

The design of the plugin should follow the general design of Figma so it looks familiar to the users. See UI2: Figma's Design System and Figma Plugin DS UI Library. Another community file with some reusable elements: https://www.figma.com/community/file/783443376634935772
