fix: error urllib.error.HTTPError: HTTP Error 308: Permanent Redirect

[claudiaifrim]

When starting a Plone instance that uses eea.ldapadmin, an error is thrown due to a permanent redirect from http to https for the SPARQL endpoint. See the error above:

FileNotFoundError: [Errno 2] No such file or directory: '/plone/instance/var/ldapdump/countries.json'

During handling of the above exception, another exception occurred:
