style(rollouts): gofmt analysisruns.go and correct the trigger label values

The comments interleaved in AnalysisRunSummary split gofmt's struct tag
alignment into separate blocks, so the original spacing no longer matched
what gofmt produces. CI's gofmt check fails on it.

The rollout-type label values in the comment were also wrong. Argo Rollouts
writes Step, Background, PrePromotion and PostPromotion, not the longer
"...Analysis" spellings.
