AT:

• Replace existing checklists with the new one:
  • String Variable Input - StringInput.js (Let's use the white theme here and override some the style to match the existing ones. We can remove them once we carbonise the modal content)
• The new checklist should work like the old component

Testing Notes:

1. create process report
2. add variable filter for string variable
3. the new carbon checklist is used in the modal and it works as the previous one
