`Client.register_plugin` inferred as NoReturn

[moi90]

Describe the issue: Because of the @singledispatchmethod Client._register_plugin (which unconditionally raises TypeError in the base implementation), pyright infers that Client.register_plugin (and therefore also Client.forward_logging) never return.

Minimal Complete Verifiable Example:

with Client() as client:
  client.forward_logging()

  # Inferred type:
  # (method) def forward_logging(
  #     logger_name: Unknown | None = None,
  #     level: int = logging.NOTSET
  # ) -> NoReturn


# Error: "Type analysis indicates code is unreachable"
...
