Allow authors to submit requests for metadata revisions

Is your feature request related to a problem? Please describe.
Sometimes authors might require to make changes to an article's metadata at various stages of the workflow. Currently, authors have to email the editors outside the system to communicate any desired changes. Then, the editor have to go and make the changes to the article metadata themselves and might need to go back and forth over email while the process takes place.

Describe the solution you'd like
A new mechanism for authors to submit metadata revisions to any of their submissions. These revisions will be stored in Janeway and a notification will be fired to the editorial team. Then, if approved, the metadata changes will be applied onto the article object.

Additional context
The metadata revision requests can be preserved even after being accepted so that editors can refer back to previous versions of the metadata or even restore the article metadata to a previous state.
It might be worth cosidering the current wofklow for preprints here, since the process seems it would be very similar.

Start by reviewing Janeway's existing preprint workflow, which the issue identifies as a possible model for this feature. Trace how metadata changes and editorial notifications currently move through that workflow. Done should include author-submitted revision requests, editorial notification and approval handling, and preservation of accepted revisions for later reference or restoration.
