Blog post about Kubewarden 1.21

[flavio]

[WIP] Topics to cover:

• Breaking change inside of Policy Server configuration file. This is relevant only to the ones running Policy Server outside of Kubernetes.
• Rust SDK: introduced Rust types of Kubewarden's CRDs
• helm chart:
  • Tagged new versions of the recommended policies to include dep updates. Updated helm chart to consume them
  • Switch to kuberlr to invoke kubectl as part of helm charts hooks
• Dependency updates - is there a way to get the number of bumps done during a milestone?
• Technical debt
• tinygo 0.35.0 support
• docs:
  • new organization and persona page
  • kwctl cli flags
  • how to verify our artifacts (if we manage to get document how to verify Kubewarden artifacts docs#490 done)
