enhance(actions): show the steps the runner reports (#39720)

Gitea derives the steps of a job from the workflow file, so the `pre`
and `post` steps of actions only show up inside "Set up job" and
"Complete job".
Fixes https://github.com/go-gitea/gitea/issues/24604.

A runner can now report the steps it actually runs, and Gitea shows
those instead. Runners that don't report them keep the current view, and
older Gitea versions ignore them.
