Failed to start using nacos as configuration center

[Elioooon]

Environment

• Server: Dubbo-go, v3.1.1
• Client: Dubbo-go, v3.1.1
• Protocol: Triple
• ConfiigCenter: Nacos: v2.2.3
• Registry: Zookeeper, v3.5.10

Issue description

When I used nacos as the configuration center for configuration, I found that the service could not be successfully registered. This causes the client to start an error.

thx,I think this is caused by the config not being merged after reading it from config center, I will fix it later
