Make it possible for the author to send revision directly

Hi @nef, I have a short memory! It looks like this came up in April and an issue got filed for it here: https://github.com/pkp/pkp-lib/issues/6900#issuecomment-930784689

I’m not sure this is a really high priority now, and I’m still in favor of the discussion-to-submission-file approach. But if any work proceeds you’ll see it on that issue.
