This is minor but would really make our team happy. Most of the built-in steps we use have infinitive case (e.g. "Spin up environment", "Check out code") but a few use the gerund form (e.g. "Preparing environment variables..." or "Restoring cache...").
Consistency is a big deal and this would be an easy fix to improve it greatly, to have all the built-in steps use consistent infinitive case (e.g. update to "Prepare environment variables", "Restore cache"...)
