Record demo

Record a brief demo of the work achieved in this PoC. It should include:

• A problem statement (i.e. reducing Renovate toil), as well as the previous work that has led up to this.
• An overview of ArgoCD's UI and how it works, linking back to the problem statement.
• Any other benefits that we'd get from this PoC being green lit.
• Where we'd like to take the PoC from here.
