perf(cli): optimize CPU consumption of help pages (#9607)

This change reduces the CPU consumption of --help by ~50%.

Also, this change removes ANSI escape codes from our golden files. I
don't think those were worth the inability to parallelize golden file tests and
global state fragility.

           starting, regardless of user activity. This is an enterprise-only
           feature. Maps to "Max lifetime" in the UI.
