fix: use https instead of http in helsinki importer

Using http seems to cause the following error:
"GDAL_ERROR 1: b'GnuTLS recv error (-110): The TLS connection was non-properly terminated.. You may set the CPL_CURL_IGNORE_ERROR configuration option to YES to try to ignore it.'"

This *should* fix the issue.
