Messy traceback if `importlib.reload()` is called with a `str`

[AlexWaygood]

Bug report

Bug description:

If you call importlib.reload() with a str, there's a huge amount of unnecessary detail in the traceback that makes it look like there's an internal error in the function itself:

>>> import importlib
>>> import typing
>>> importlib.reload("typing")
Traceback (most recent call last):
  File "/Users/alexw/.pyenv/versions/3.13.0/lib/python3.13/importlib/__init__.py", line 101, in reload
    name = module.__spec__.name
           ^^^^^^^^^^^^^^^
AttributeError: 'str' object has no attribute '__spec__'. Did you mean: '__doc__'?

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/alexw/.pyenv/versions/3.13.0/lib/python3.13/importlib/__init__.py", line 104, in reload
    name = module.__name__
           ^^^^^^^^^^^^^^^
AttributeError: 'str' object has no attribute '__name__'. Did you mean: '__ne__'?

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<python-input-2>", line 1, in <module>
    importlib.reload("typing")
    ~~~~~~~~~~~~~~~~^^^^^^^^^^
  File "/Users/alexw/.pyenv/versions/3.13.0/lib/python3.13/importlib/__init__.py", line 106, in reload
    raise TypeError("reload() argument must be a module")
TypeError: reload() argument must be a module

We should probably suppress the exception context here.
