JSV: Switch to the new ui-kit and updated design

[marbemac]

We're building out a refreshed design system, and improving consistency across the board. Update the schema viewer component to use the new design system.

Design: https://www.figma.com/proto/IkNc59AU2JN5Kc1qbd2AiB/Elements?node-id=681%3A242&viewport=302%2C436%2C0.980905294418335&scaling=min-zoom

DOD:

• schema viewer component uses components from mosaic. dependency on old ui-kit is removed

Out of scope:

• Any major behavioral changes. Implement as much as you can using just mosaic components and CSS, the rest will be handled in separate issues.

This is blocked by the nonexistence of the new ui-kit, right? Is there an issue tracking that?

@marcelltoth Ok, mosaic now exists and whilst not all the components are ready, this is blocked by the entire epic which might not be accurate.

Can we figure out which specific mosaic components its blocked by so this will become unblocked when they're done?

[marcelltoth]

I changed it to be blocked by the spike proving mosaic works. We may need other dependencies as well, let's talk about this during our next sync
