Allow recovering a normalized version of workflow request state from API

[jmchilton]

Implements #18981

Also made small improvements to the schema for running workflows. Filled in a bunch of stub descriptions, dropped step_parameters which never existed in the API. There is a random check that it isn't in the request because it a field that is included in the test format - but it shouldn't have been part of the schema.

I've included a sort of breaking change to the workflow invocation API here - it is isolated to cc8f1b6. If you call a workflow by workflow ID and not a stored workflow ID - I think you should run that workflow and not the latest workflow. It feels quite jarring to say this is the particular instance ID I want to run and then get the latest version IMO. In either case if you explicitly pass a version - it will still run the workflow at that version.

Rerunning a failed test here - I haven't seen this before and it might be related.

I have seen this quite a few times, I don't think it's related
