Replace Dev-tool components with Primer Components  #38

We are rewriting css instead of using primer components -- this will lead to issues down the line if primer has a redesign. It would be nice to use primer components to avoid future issues and keep consistency.

We may need to spike this idea out. I am not actually sure how easy it is to use design system components inside a chrome extension since importing in a chrome extension is challenging.

Acceptance Criteria

• Replace buttons with primer button
• Replace links with primer link
• Utilize Primer color values
