pkp/pkp-lib#10263 Relax editing metadata on published/posted materials

fixes #10263

[asmecher]

The workflow still includes a Vue file called WorkflowPublicationEditDisabled.vue, but with these changes, it's used to present a warning, rather than a prohibition against editing. The filename should be adjusted -- but watch out in case this is also used in the author interface; I didn't check. If it is used there, then "disabled" is still appropriate; it might be necessary to either make a copy for the editor's interface under a different name, or generalize it to either warn or prohibit changes.
