No need to display access endpoints for a normal chart

[zzxwill]

Describe the bug

Locally installed a Chart crossplane, and there is access endpoints shown after the installation, which is not necessary as we don't access it from anywhere.

➜  addons git:(crossplane) ✗ vela addon enable ./crossplane
enable addon by local dir: ./crossplane
I0613 16:30:53.057039    4400 apply.go:107] "creating object" name="addon-secret-crossplane" resource="/v1, Kind=Secret"
Addon: crossplane enabled Successfully.
Please access the crossplane from the following endpoints:
I0613 16:31:49.468440    4400 utils.go:156] find cluster gateway service vela-system/kubevela-cluster-gateway-service:9443
+---------+-----------+--------------------------+----------+
| CLUSTER | COMPONENT | REF(KIND/NAMESPACE/NAME) | ENDPOINT |
+---------+-----------+--------------------------+----------+
+---------+-----------+--------------------------+----------+
