CVoc retrieval filtering enhancement

[qqmyers]

What this PR does / why we need it:
Dataverse's external vocabulary mechanism includes an option for Dataverse to retrieve and cache metadata about a given vocabulary/PID indentifier by calling an external service (e.g. ORCID, ROR, SkosMos, OntoPortal) and filtering the returned JSON results to get the desired subset of information. As the range of examples has expanded, the syntax for specifying that filtering is being expanded. For example, #11762 allows retrieving the nth entry in a JSON array rather than the whole array.

This PR extends a related functionality which allows retrieving a JSON object from an array based on a matching key:value pair, i.e. one can retrieve the object with the key:value "mykey":"myval" by specifying /mykey=myval as part of the path in the filter "params" entry. Currently this functionality only works if the value of the key is a JSON String. However, with the ROR v2 API, we have a case where we'd like to retrieve the object which has the value "ror_display" for the "types" key where "ror_display" is a string within a JSON array of values. (The entry with the "ror_display" is the organization name that is used for display on the ROR page and is nominally the canonical name for the organization.

This PR modifies the parsing in Dataverse to support this case. As the ROR v2 updates are included in the gdcc/dataverse-external-vocab-support repo, examples and further description of the retrieval-filtering syntax will be added there.

Which issue(s) this PR closes:

• Closes #

Special notes for your reviewer: Nominally we want ROR v2 support to work well before v1 is retired in Dec. 2025.

Suggestions on how to test this: Configure a field to use the ROR v2 script (as in #46 and change the termName/params entry to be /names/types=ror_display/value (instead of /names) and verify that the OAI_ORE export includes the name of the organization (e.g. for author affiliation) and that the DataCite xml export also includes it.

Does this PR introduce a user interface change? If mockups are available, please link/include them here:

Is there a release notes update needed for this change?: I'll add a generic one to say that this version extends the retrieval-filtering - to cover both this and #11762.
