This PR can be acceptance tested by following these steps:

In a fresh site that has not Site Kit already or the feature flag enabled from the Yoast test helper, smoke test the following parts of the Site Kit integration:

• First confirm that the value of the wpseo option array has the site_kit_configuration_permanently_dismissed sub-setting as 0 and then do the following POST request: https://example.com/wp-json/yoast/v1/site_kit_configuration_permanent_dismissal
  • Set the request body as follows { "is_dismissed": true }
  • Verify you get a successful response
  • With a MySQL inspect the value of the wpseo option array in the wp_options table
    • Verify that site_kit_configuration_permanently_dismissed is set to 1
  • Reset options after that
• Now start the onboarding flow and once you setup Site Kit , make sure you are redirected to our dashboard and greeted by this alert:

• Before giving consent as the last step of the onboarding, check your wpseo option and confirm that you see the last_interaction_stage sub-setting have the grantConsent value
• Give consent as the last step of the onboarding and open a new tab. Confirm that you see the site kit widgets working.
