This task is part of the effort to rework the Starter Page Template Picker for new pages. This part of the initiative will focus on utilizing the data fetched from /wpcom/v2/sites/{site}/block-layouts to replace the static data used in #2437, and #2436 with the results from the API.

Note: Work for caching this data will be handled in Add Issue but consideration for migrating this to use the cached data should be considered.

Goals

• Data should be fetched from the endpoint developed as part of Add API Endpoint containing the current with starter page layouts #2413
• The UI components developed as part of [Modal Layout Picker] Create Layout Picker category bar UI using static data #2437, and [Modal Layout Picker] Create Layout Picker sections and thumbnail UI using static data #2436 should be updated to utilize the results of the API
• Self-hosted sites should still use the static data, and shouldn't make the API request.
