This is a small tweak to avoid adding the callable `Type` on the error value itself. Namely, it's always available regardless of the error, and it's easy to pass it down explicitly to the diagnostic generating code. It's likely that the other `CallBindingError` variants will also want the callable `Type` to improve diagnostics too. This way, we don't have to duplicate the `Type` on each variant. It's just available to all of them. Ref https://github.com/astral-sh/ruff/pull/16239#discussion_r1962352646
