[pve-devel] [PATCH proxmox_dart_api_client 2/2] fix: ios: add explicit throw of `HandshakeException`

[Shan Shaji]

The `cupertino_http` package is throwing `ClientException` [0] instead
of `HandShakeException` when the certificate is not valid.

Due to this the exception was directly shown in the UI. Inorder to make
the error more user friendly catch the `NSErrorClientException` and
rethrow `HandShakeException` if the certificate is not valid.
