Deprecate 'publisher' field on journal

[amruelama]

As we have added 'publisher' as a contributor (#548) for all the journals in GCIS, we need to remove 'publisher' field. Downloaded backup.

Deprecating rather than removing, to avoid breaking tools.

GUI will no longer offer up the field.

@amruelama this is live on data-dev for your review.

Looks perfect on dev!

@lomky Reopening this issue because, even though the 'publisher' field is deprecated and the data is removed, the related data is still available when downloaded as csv, json and other formats. Is it possible to either remove the data completely or add the relevant publisher in the downloadable data? We did a clean-up before deprecating the field and relating the relevant org as 'publisher'. We also populated missing publishers as a part of (#548)

Change done on stage @amruelama.
