fix(example): add protocol tcp for workaround ComparisonError.

[mztnnrt]

Hi, as for the community, we are grateful for your daily contributions.

Now we are using argo-rollouts and argo-cd, when apply the sample code, we have the error which is displayed argo-cd console.

Failed to compare desired state to live state: failed to calculate diff from cache: error calculating structured merge diff: error building typed value from config resource: .spec.template.spec.containers[0].ports: element 0: associative list with keys has an element that omits key field "protocol" (and doesn't have default value)

So we add the protocol, If it is suitable for merging, please merge it.
