[Bug]: the attu service port in attu-svc.yaml (helm chart template file) does not value the values.yaml or command parameter

[carusyte]

Describe the bug: Unable to specify attu service port during helm installation either thru customized values.yaml file or "--set" flag Expecting users should be able to specify custom port for attu and override the default port 3000 checked the attu-svc.yaml template file and found that the port is hardcoded instead of reading from values.yaml

Steps to reproduce:

1. run the following command to deploy milvus+attu via helm helm install milvus-01 milvus/milvus --set attu.enabled=true --set attu.service.type=LoadBalancer --set attu.service.port=80

2. then run the following command and found that the attu service port is still 3000. kubectl get svc -A

Attu version: along with milvus-4.0.29
