chore(cli): more accurate message to garbage collection prompt

[kaizencc]

Should look like this:

Found 1 image to delete based off of the following criteria:
- images have been isolated for > 0 days
- images were created > 0 days ago

Delete this batch (yes/no/delete-all)? 

Instead of this:

Found 1 assets to delete based off of the following criteria:
- assets have been isolated for > 0 days
- assets were created > 0 days ago

Delete this batch (yes/no/delete-all)?
