[issue22547] Implement an informative `BoundArguments.__repr__`

[Yury Selivanov]

Yury Selivanov added the comment:

Actually, I like the current repr (minus the object ID, I'll update the code).

The thing about BoundArguments is that '.arguments' is the main property. You use it to add more stuff to *args & **kwargs, or to add/remove positional/keyword arguments.  Seeing a flattened call signature in the repr won't help you with debugging.

Perhaps, we can implement __str__ using your approach.
