Remove Name & Path from excluded params on Group Import

What does this MR do?

This MR removes name & path fields from group_import_export.yml. These fields are actually required during group structure restoration, specifically when creating sub groups.

It fixes a bug when Group Import is performed with a group structure containing subgroups, subgroups creation fails due to name and path params missing. Since we filter those params out.

Resolves #206927 (closed).
