Description:
Pywikibot tests fail with UnknownSiteError for language code vro during test_pagelanglinks. This is because the language vro (Võro) — corresponding to the fiu-vro Wikipedia (https://fiu-vro.wikipedia.org) — is missing from the Wikipedia family definitions (wikipedia_family.py).
Error snippet
pywikibot.exceptions.UnknownSiteError: Language 'vro' does not exist in family wikipedia
Context:
The fiu-vro wiki is a valid Wikimedia project (Võro Wikipedia).
The language code vro appears in langlinks returned by the API or Wikidata, but Pywikibot’s family files do not list it.
This causes errors when Pywikibot attempts to create Site instances for vro.
Suggested solution:
Add fiu-vro or vro -> fiu-vro to code_aliases in family.py.
Tests:
Ensure test test_pagelanglinks handles this gracefully: tests.site_generators_tests.TestSiteGenerators.test_pagelanglinks
