HTML Attributes Customizer for Blocks

• Replace group_inner with reusable first_div inner strategy (Group, Cover, and filter extensions).
• Run Group inner attributes on render_block_core/group at priority 999 (after core and other plugins).
• Tested up to WordPress 7.0.

1.0.1

• Fix Group block inner attributes applying after wp_restore_group_inner_container and other render_block_core/group filters (priority 999).
