Limit concordances to vocabularies included in a Cocoda instance #763
Description
The list of concordances is getting longer and longer. There should be a configuration setting to only show concordances between terminologies configured in the current Cocoda instance. For instance at https://coli-conc.gbv.de/cocoda/sbb/ we don't include STW nor GND so concordance GND-STW should not be shown.
