[3.1] Fix group key in Nacos Service Discovery

[AlbumenJ]

What is the purpose of the change

In Dubbo 2.7.x, the group value configured on the Nacos Registry URL is aligned with the group in the Nacos registry. (group can be used as a soft isolation similar to namespace)

In Dubbo 3.0.x, the group configured on the Nacos Registry URL is not used by default, and all use DEFAULT_GROUP. (group no longer provides isolation)

In Dubbo 3.1.x, the group value configured on the Nacos Registry URL will realign the group grouping in the Nacos registry.
