Workaround to allow use of ed25519 keys on Azure

* Allow passing a dummy RSA key to Azure to satisfy its obtuse
requirements (recommend deleting the corresponding private key)
* Then `ssh_authorized_key` can be used to provide Fedora CoreOS
or Flatcar Linux with a modern ed25519 public key to set in the
authorized_keys via Ignition

 ## Latest
 
+## v1.28.2
+
+* Kubernetes [v1.28.2](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.28.md#v1282)
+* Update Cilium from v1.14.1 to [v1.14.2](https://github.com/cilium/cilium/releases/tag/v1.14.2)
+
+### Azure
+
+* Add optional `azure_authorized_key` variable
+  * Azure obtusely inspects public keys, requires RSA keys, and forbids more secure key formats (e.g. ed25519)
+  * Allow passing a dummy RSA key via `azure_authorized_key` (delete the private key) to satisfy Azure validations, then the usual `ssh_authorized_key` variable can new newer formats (e.g. ed25519)
