Allow editors to identify the canonical data package in the Editor

Once we've implemented a way to display the canocial dataset on the dataset landing pages (#2541), then we should add a way for users to identify these originals when they exist.

Proposed solution

• Add a checkbox next to the "Alternative Identifier" input in the editor to allow users to flag a dataset as the original/source dataset when the one in MetacatUI is essentially a duplicate
• When checked, MetacatUI will automatically apply schema.org:sameAs and prov:derivedFrom annotations with URL with the DOI/UUID of the original as the object.
• The alternative identifier must be a valid URL to allow the annotations to be generated correctly (where as alternative identifier in EML is not as strict).

Reminder: test how regular annotations appear when they are not bioportal identifiers as they all are currently.
