Metadata 4.5 - GraphQL/Akita updates

Because the new publisher data structure will no longer be compatible with the GraphQL schema:

[ ] A new GraphQL publisher type may need to be implemented.
[ ] Queries in other GQL types (ex doi_type) may need to be updated.
[ ] Any existing queries (in akita, for example) may need to be adjusted to the new publisher data structure.
[ ] If any templates or logic in akita relies on publisher metadata, these will need to be adjusted to the new data structure.
