Only fetch steps and trigger for the current workflow version (#15003)

Avoid fetching full steps and trigger for versions that are not the
current version. Because those won't be used anyway. Better for
performances.

Only difficulty was for the `createDraft` mutation. I needed to return
the full created version so I can store it in cache and use it as new
`currentVersion`. Otherwise the current version is considered as
incomplete for a short time, since workflow is fetched separately from
the current version.
