Use latest pre-built images to start karmada cluster

[warjiang]

What happened:
In this PR: #5627
introduced the feature to install karmada cluster with pre-built images, when I execute the following command:

BUILD_FROM_SOURCE=false hack/local-up-karmada.sh

it outputs:

it seems that the scripts still check go, the go build tools seems only work when invoke make images:

but if we use pre-built images, why we still need to check go

What you expected to happen:
skip check go when install from source

How to reproduce it (as minimally and precisely as possible):

git clone [email protected]:karmada-io/karmada.git
cd karmada
BUILD_FROM_SOURCE=false hack/local-up-karmada.sh

Anything else we need to know?:

Environment:

• Karmada version:
• kubectl-karmada or karmadactl version (the result of kubectl-karmada version or karmadactl version):
• Others:
