Make CEUR-WS entries compatible to entries created by CEUR-WS bot

[WolfgangFahl]

Is your feature request related to a problem? Please describe.
There seem to be to ways to identify the volume of a CEUR-WS proceedings volume:

1. Using published in and a Volume tag
2. Using partof the series and a Volume qualifier

Describe the solution you'd like
In any case the part of the series and qualitifer should be set - the other setting is optional

Describe alternatives you've considered
Querying for bother ways in SPARQL but that is tedious

Additional context
This if for checking the consistency between the CEUR-WS single point of truth and Wikidata

I am almost done with fixing:

left	↔	right	#	%
wikidata	←	local	3	0.08%
wikidata	↔	local	3591	99.92%
wikidata	→	local	0	0.00%

There are only

• https://ceur-ws.org/Vol-3447 Vol-3447 urn:nbn:de:0074-3447-8
• https://ceur-ws.org/Vol-3462 Vol-3462 urn:nbn:de:0074-3462-7
• https://ceur-ws.org/Vol-3526 Vol-3526 urn:nbn:de:0074-3526-1

to be fixed and if this Feature request is implemented the problem should not show up again in the future.

The query i am using for sync checking is
