Wrong secret name in the Helm template of the egressgateway

[vadimeisenbergibm]

Describe the bug

Egress gateway Helm template contains istio.default as the secret name, should be istio.istio-egressgateway-service-account. The bug is fixed in master by #6350 on master , I would like to have it in 0.8.1.

Due to the wrong secret name, mTLS between a sidecar proxy and the egress gateway will fail.

Expected behavior
Directing egress traffic from an application pod to the egress gateway should work when Istio is deployed with mTLS.

Steps to reproduce the bug
Follow the steps in istio/istio.io#1605 for Istio with mTLS.

Version
The release 0.8.0.

Is Istio Auth enabled or not?
Yes.

Environment
Kubernetes.

@hklai I see, will do.

As noted in #5982, we do not intend to cut 0.8.1 anymore since 1.0 is right around the corner.

Closing this for now.
