Checkout: add ad-free experience to plan features

[aneeshd16]

Proposed Changes

• Adds Ad-free experience to the feature list for the Personal plan on the checkout page. This change was meant to support this experiment( pbxNRc-2Hx-p2 ), but I feel it would benefit all users. This string is already translated and displayed in the plans grid.

Testing Instructions

• Go to /checkout/<site slug>/personal-bundle where <site slug> is for a site on the free plan.
• Confirm that the sidebar copy matches the screenshot.

Pre-merge Checklist

• Has the general commit checklist been followed? (PCYsg-hS-p2)
• 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)?
• For changes affecting Jetpack: Have we added the "[Status] Needs Privacy Updates" label if this pull request changes what data or activity we track or use (p4TIVU-ajp-p2)?

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

Sections (~12 bytes added 📈 [gzipped])

name      parsed_size           gzip_size
checkout        +32 B  (+0.0%)      +12 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.

Async-loaded Components (~24 bytes added 📈 [gzipped])

name                                             parsed_size           gzip_size
async-load-calypso-my-sites-checkout-modal             +32 B  (+0.0%)      +12 B  (+0.0%)
async-load-calypso-blocks-editor-checkout-modal        +32 B  (+0.0%)      +12 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.
