   I wrote a single big PR to show how the code can look like: PR gh-129359.

   I propose to use replace PyErr_WriteUnraisable() with PyErr_FormatUnraisable() to log better (more helpful) error messages.

   The drawback is that it changes sys.unraisablehook arguments: the object is no longer set. In my PR, I had to update multiple tests to check err_msg (string) instead.
