Architecture Diagram and Doc should also be updated

@Pothulapati now that 2.10.0 has been released, should we close this issue or are there outstanding doc items here that we should take care of?

[Pothulapati]

@adleong There are a couple of doc updates still in flight i.e

• Flagger Canary
• ArgoCD

Both of the above require changes in external repos, and I am tracking them. Will close this once they are fixed.

[adleong]

@Pothulapati any update on these? since these changes are already tracked externally, should we close this tracking issue?
