Editor: Fix preloaded REST API paths

When providing an incorrect path to preload, the `rest_preload_api_request` will silently fail, and nothing will be preloaded.

* Fix typo for `wp_template_part` post type preload path for the Site Editor.
* Do not preload the `wp_block` post type for post editors. The endpoint doesn't support unbound queries, and the data is no longer needed during editor initialization.
