Fix deprecated command for make minikube-push

[govargo]

What type of PR is this?

/kind cleanup

What this PR does / Why we need it:

When I deploved agones and tried to use minikube cluster, I found the deprecated warning for minikube cache.
And current make minikube-push command will push to minikube profile, because the profile agones is not defined.

This PR fix to use minikube image load and add the cluster profile.

% make minikube-push
minikube cache add gcr.io/agones-images/agones-sdk:1.24.0-3e5f17f-linux-amd64
❗  "minikube cache" will be deprecated in upcoming versions, please switch to "minikube image load"

❌  ...cluster "minikube" does not exist

Which issue(s) this PR fixes:

None

Special notes for your reviewer:

If you think $(MINIKUBE_PROFILE) is not needed, please let me know.
