Add support for naming tasks in .run effects

[aregler]

Hi 👋🏻

In Swift 6.2 the naming of Tasks was introduced in SE-0469.
This proposal allows developers to assign human-readable names to tasks, which show up in debugging and profiling tools.

I think this also could be useful when working with the .run effect in TCA.

Usage

case .tapped:
   .run(name: "🔄 Button tapped response-task ") { send in
      await send(.response)
}

Example:

Thank you for all your great work,
