Fn.getVocabularyLabel should handle hierarchical vocabulary ids

A valid id for a hierarchical vocabulary entry is "PARENT_ID/CHILD_ID". However, the Fn.getVocabularyLabel platform function does not recognise this id and returns it verbatim.

Expected Result:

Fn.getVocabularyLabel("country", "europe/France") -> "label.directories.country.France"

Actual Result:

Fn.getVocabularyLabel("country", "europe/France") -> "europe/France"

Workaround:

Split the vocab id by separator, and provide the child id only e.g.

Automation:

var id = input["schema:field"].split("/")[1];
Fn.getVocabularyLabel("country", id); // "label.directories.country.France"

FreeMarker:

<#assign k=Document['schema:field']?split('/')?last />${Fn.getVocabularyLabel('country', k)}

Caveat: need to check the property actually has a value, which creates additional complexity and should be handled automatically by the platform function.
