[PATCH proxmox_dart_api_client 1/1] cleanup: avoid print statements

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

Dart linter rules recommend avoiding print statements [0]. To align with
this, remove all print statements. The lints recommended.yaml config [1]
does not have the rule by default so explicitly add it.

- [1] https://github.com/dart-lang/core/blob/main/pkgs/lints/rules.md
