Update hbzId

[acka47]

Here is the current description:

lobid-vocabs/lobid-vocab.ttl

Lines 393 to 394 in ae7b414

	rdfs:comment "HT-Nummer. Der Identifier, der einer bibliographischen Ressource im hbz-Verbundkatalog zugewiesen wurde."@de ;
	rdfs:comment "The identifier that is assigned to a bibliographic resource in the hbz union catalogue."@en ;

This isn't correct anymore as by now the Alma-MMS-ID is the main ID in the union catalogue. We will have to update the description.

We should discuss whether rdfs:label also needs adjustment.

What's wrong with this description? Except that ZDB titles are no longer assigned an hbz ID.

The Alma MMS ID is a vendor-specific identifier, the hbz ID is vendor-independent. At least in my understanding.

I want to second that. Only records that are "truly" or were records in the "Verbundkatalog" get a hbzId. ALMA has a lot more records than the NZ/Verbundkatalog also CZ and local records. All of them have almaMmsIds but none of them have a hbzId.
