Create a Carousel layout style (frontend & backend) based for the Covers block.

Requirements:

• Implement the frontend UI based on the Design System
• Follow the backend UX recommendations and usability testing results
• Follow the prototype for the interaction behaviors and animations.
• Follow the wireframes recommendations (see screenshots).

Specs:

• The Carousel option should be selected by default when users create a new block.
• The "rows to display" section should be hidden when the Carousel layout is selected.
• Replace the "select tags" field by a dropdown menu where we can choose from available tags. This way users don’t have to remember which tags exist.
• We could display a placeholder image instead of an error message when the content block is empty, so that users could quickly visualize how the block looks like even without content.
• We should set by default 12 items maximum for the carousel layout. This should not be editable.
• Add a section to enable a "view all" link.
• Add a characters limit to 120 characters for the Description field.
