@aaronware Can you review these updates?

I updated the init hook to enqueue_block_editor_assets. With that, I also removed the logic within the hooked function (block_scripts) to check for admin and post type. The block editor does not have context to the $_POST and these checks were preventing scripts from loading anywhere.

I noticed console errors for the admin CSS, but the file does not exist within the last few releases. I downloaded an older version and see the admin style we did introduce were very minimal and not necessary.
