2FA Setup: Use vertical nav instead of radio buttons

[rcrdortiz]

Part of:

• DOTCOM-13063

Proposed Changes

• Refactored the 2FA setup from using radio buttons and a next/continue button to using a more streamlined approach by relying on the vertical navigation component we have available in our design library.
• Refactored the component from a Class component to a Functional component.

Here is how your PR affects size of JS and CSS bundles shipped to the user's browser:

Sections (~55 bytes added 📈 [gzipped])

name      parsed_size           gzip_size
security       -566 B  (-0.1%)      +55 B  (+0.0%)

Sections contain code specific for a given set of routes. Is downloaded and parsed only when a particular route is navigated to.

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.
Gzip Size: Compressed size of the JS and CSS files. This much data needs to be downloaded over network.

We distribute the Card component to avoid boxes within boxes.

Nice! thanks for the updates. Looks good on my end.

I see we're still using grid icons but that is happening within the component we're using. We can follow up with a separate update to change all the icons at another point.
