Add pricing page and components

[katjuell]

Adds pricing page and related components and closes #62. Does not bring over PricingFreeTierPopover and HoverablePopover as they were not need/used (updated in #48)

To Test

• Check out the branch and update local dependencies with npm ci
• Head to the /pricing page and make sure everything looks as expected
• Test on static builds
• Ensure no console warnings from anything to do with this PR

Forgot to mention, I'm seeing this error in the console:

When server rendering, you must wrap your application in an <SSRProvider> to ensure consistent ids are generated between the client and server.
