edge-23.4.3

This edge release improves compatibility with ArgoCD by changing the Linkerd
control plane to create Lease resources at runtime rather than including them
in the Helm chart. It also addresses a CVE by upgrading an underlying
dependency.

• Upgraded h2 dependency to address CVE-2023-26964
• Fixed an issue where server_port_subscribers metric in the Destination
  controller was sometimes absent
• Removed the policy-controller-write Lease from the control plane Helm chart in
  favor of creating it at runtime
• Updated the proxy-injector to pass opaque port lists to the proxy as ranges
  rather than individually, greatly reducing the size of proxy manifests when
  large opaque port ranges are set
• Fixed an issue where the proxy was performing protocol detection on ports
  marked as opaque
• Improved backwards compatibility between 2.13 proxies and 2.12 control planes
