Fix: change WorkflowStep into an abstract class

[LuisDuarte1]

For some reason, Typescript resolves types in a different away compared to abstract classes. As a consequence, it would not apply the overloading properly and always treats WorkflowStep.do as a 3 argument function

LGTM assuming this works. Have you tried generating the types with this and examined them or is it more of a guess-and-check situation?

Good question. To avoid thrashing, let's generate these and test locally on smoke tests @LuisDuarte1

I have overridden my local worker-types to see if it works, so no worries here

Then no worries here either, but it looks like it can't be merged yet because "This branch has conflicts that must be resolved"
