[PATCH proxmox_dart_api_client 2/2] deps: add objective_c dependency to access NSError's code property

[Shan Shaji <s.shaji@proxmox.com>]

Starting from `v9.0.0` of the `objective_c` package, `NSError` is defined
as an extension type [0] instead of a wrapper class in Dart. As a result, the
`code` property is not accessible at compile time unless the extension
type is explicitly imported, even though the underlying object exposes
it at runtime.

To fix this, the `objective_c` dependency has been added and imported the
dependency were the code property is accessed.
