Designs for "Browse Addons" Modal

[zelcion]

Description

This first version of the Browse Addons modal won't use a service to search through already validated Addons, which means we will instead just pick an origin for the addon, and a path/location/name for it. This will download or import the addon and validate it locally.

Steps

• [x] Create feature Requirements
• [x] Design Modal

Requirements

• When opening, the modal comes empty with a selection to pick from: Addon from Disk, Addon from NPM, or CDN.
• There's a field to type the path/package name/url.
• When "from disk" is selected, input is a file picker.
• there is an import button that is only active when both fields are filled.
• After clicking the button, importing and validating process is started.
