#13493864 WordAds: Include Inline Ads Setting

Fixes #90997

Proposed Changes

Adds the “Inline within post content” settings to the WordAds dashboard on Calypso.

Why are these changes being made?

These changes were already recently added to Jetpack in WP-Admin: Automattic/jetpack#37170. This PR brings parity with Calypso.

Testing Instructions

1. Visit /earn/ads-settings/ and confirm that the setting is listed there
2. Toggle the setting
3. Visit /wp-admin/admin.php?page=jetpack#/earn, and confirm that the toggle updates to match Calypso.
4. You can also toggle the setting in WP-Admin and ensure that it is reflected upon refreshing Calypso.
