As a user I would like to understand what I am deleting and avoid deleting things by mistake

ACs:

• Update the delete confirmation title to be dynamic depending on what content is being deleted:
  • Single item selection: "Mark this item for deletion?"
  • Multi-selection: "Mark these items for deletion?"
• Change the intro text to: This item and its sub-items will be marked
for deletion
• Add title to the dependencies list: Broken links
• Change the intro text to: The following content items link to what you’ve marked for deletion. If you continue, these links will break.
• CTA buttons
  • "Mark for deletion" is the default, on the right, and the button color is white
  • "Cancel" is on the left, and the button color is yellow 
    • Update the button text to be black for accessibility purposes
