Add two new solutions to the cancellation flow

[taggon]

Proposed Changes

• This PR adds two new solutions - Live Chat and Built By - to the cancellation flow and also applies fresh visual styles to the flow as a part of the Cancelation Reason/Solutions project. For more details, see pebzTe-kL-p2

Testing Instructions

• Try to cancel/remove your paid plan.
• You would be taken to the solutions based on the reason you picked. Visit pebzTe-nt-p2 to see the reasons and the relevant solutions. For example, you will see the Downgrade to Monthly Plan solution when you choose Price/Budget > It's too expensive.
  
  
• Make sure the buttons work properly.
• For testing LiveChat, see pebzTe-sj-p2

Pre-merge Checklist

• Have you written new tests for your changes?
• Have you tested the feature in Simple (P9HQHe-k8-p2), Atomic (P9HQHe-jW-p2), and self-hosted Jetpack sites (PCYsg-g6b-p2)?
• Have you checked for TypeScript, React or other console errors?
• Have you used memoizing on expensive computations? More info in Memoizing with create-selector and Using memoizing selectors and Our Approach to Data
• Have we added the "[Status] String Freeze" label as soon as any new strings were ready for translation (p4TIVU-5Jq-p2)?

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

App Entrypoints (~20 bytes added 📈 [gzipped])

Details

name           parsed_size           gzip_size
entry-stepper       +120 B  (+0.0%)      +23 B  (+0.0%)
entry-main          +120 B  (+0.0%)      +23 B  (+0.0%)

Common code that is always downloaded and parsed every time the app is loaded, no matter which route is used.

Sections (~728 bytes added 📈 [gzipped])

Details

name            parsed_size           gzip_size

Async-loaded Components (~45 bytes added 📈 [gzipped])

Details

name                                           parsed_size           gzip_size
async-load-calypso-blocks-inline-help-popover       +337 B  (+0.0%)      +45 B  (+0.0%)

React components that are loaded lazily, when a certain part of UI is displayed for the first time.

Legend

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.

Hi there! Noticed a small typo in this PR.

You will lose your free domain registration since that feature is only included in annual/biennual plans.

biennual --> biannual.

Hey! 👋 I found an issue with this component while working on #78711. Essentially, if href is provided, then a is rendered instead of a button. This means disabled cannot be accepted. However, I see we have an onClick method as well.

There are two conflicting solutions. Could you let me know which should be used?

1. Remove the href because it isn't a link
2. Remove disabled because it isn't a button
