[ENG-6434] Show/hide file upload page on preprint submit workflow

[futa-ikeda]

• Ticket: ENG-6434
• Feature flag: n/a

Todo

• Add some sort of acceptance test so you can keep these workflows correct

Purpose

• Add logic to show/hide the file upload step on the preprint submission/edit workflow

Summary of Changes

• Add a new flag displayFileUploadStep that controls whether or not the file upload step is shown
  • Should be shown for initial preprint submission
  • Should be shown for rejected preprint re-submission

Screenshot(s)

• Create new preprint workflow showing the file upload step
  

• Edit and resubmit workflow showing the file upload step
  

• Editing an existing preprint no longer showing the file upload step
  

Side Effects

• Editing an accepted preprint will now no longer show the option to upload a new file version

QA Notes

[futa-ikeda]

When this component is invoked in the "Edit an existing preprint" workflow (this.args.preprint being truthy in line 68), this bit of logic will be triggered. If the preprint that is passed in has reviews_state: 'rejected', the File upload step will be shown, otherwise the File upload step will be skipped

LGTM 🎆

In addition, appreciate the intuitive design of our preprint state machine.

Hooray for tests!
