fix: update service_conf.yaml.template (#8863)

fix: modify the connection ports of minio and redis in
service_conf.yaml.template

### What problem does this PR solve?

If you modify the external ports of minio and redis in the .env file, it
will also affect the connection ports inside the container in the
service_conf.yaml.template file, which is unreasonable.
