[Frontend] Update linked SPP query

Why are we doing this work

After adding new property to a query we need to update

ee/app/assets/javascripts/security_orchestration/graphql/queries/get_spp_linked_projects_namespaces.graphql

Instead of securityPolicyProjectLinkedNamespaces we need to use securityPolicyProjectLinkedGroups
