Vendure Workflow Generation Tool

[dalyathan]

Is your feature request related to a problem? Please describe.
We added some new Order states and I was wondering if there is an easier way(a tool, maybe) to generate an Order Workflow diagram just like that found in the vendure docs.

Describe the solution you'd like
@dlhck mentioned that something like that could potentially be implemented using a tool like Graphviz: https://graphviz.org/

We might also use Mermaid for that: https://mermaid.js.org/config/usage.html
