DCAT / Update Licence EU Vocabulary

[streino]

This is a preemptive PR that will be required on the next GeoNetwork License EU vocabulary upgrade (decided to go with vocabulary update on that PR).

Newer versions of the License EU vocabulary contain Concept elements with several exactMatch occurrences.

For instance :

<skos:Concept rdf:about="http://publications.europa.eu/resource/authority/licence/ETALAB_2_0"
             at:deprecated="false">
  ...
  <skos:exactMatch rdf:resource="https://spdx.org/licenses/etalab-2.0.html"/>
  <skos:exactMatch rdf:resource="https://www.etalab.gouv.fr/licence-ouverte-open-licence/"/>

The current XSLT raises the following error:

Traceback (most recent call last):
...
Error at char 108 in expression in xsl:variable/@select on line 158 column 113 of dcat-core-access-and-use.xsl:
  XPTY0004  A sequence of more than one item { ("https://spdx.org/lic ...
  CC-BY-NC-SA-1.0.html", "http://creativecommo ... censes/by-nc-sa/1.0/") } is not allowed
  as the first argument of fn:matches(). Found while atomizing the first operand of '!=' in
  {$euDcatLicense} on line 160

Tested with licences-skos.rdf version 20241211-0 (latest so far).

Looks good but should we also update the vocabulary to the latest version https://github.com/geonetwork/core-geonetwork/blob/main/schemas/iso19115-3.2018/src/main/plugin/iso19115-3.2018/formatter/dcat/vocabularies/licences-skos.rdf ?

Sure!
Are there tests I need to run to validate that upgrade, or do I just push the new licences-skos.rdf version?
Also, should I do the upgrade here or in another PR?

Formatter tests for DCAT are defined here https://github.com/geonetwork/core-geonetwork/blob/main/services/src/test/java/org/fao/geonet/api/records/formatters/FormatterApiTest.java#L89-L97

Sounds fine to update the vocabulary here.
