Version Missing in istioctl after Canary Upgrade

[danehans]

Bug Description

istioctl does not display the version after performing a canary upgrade:

istioctl version
client version: 1.11.1
istiod version: 1.11.1
pilot version: 1.10.4
data plane version:  (1 proxies), 1.10.4 (3 proxies)

I expected:

istioctl version
client version: 1.11.1
istiod version: 1.11.1
pilot version: 1.10.4
data plane version:  1.11.1 (1 proxies), 1.10.4 (1 proxies)

The same for proxy-status:

istioctl ps                                                          
NAME                                                   CDS        LDS        EDS        RDS        ISTIOD                             VERSION

Version

istioctl version
client version: 1.11.1
istiod version: 1.11.1
pilot version: 1.10.4
data plane version:  (1 proxies), 1.10.4 (3 proxies)

Additional Information

I'm following the operator-based canary upgrade documentation.

This is not a bug. I was not including the ISTIO_META_ISTIO_VERSION was empty when building my container image.
