other examples of module dunder AttributeError:

this one doesn't use {name!r} but '{name}':

interestingly, this is actually the correct form:

>>> getattr(types.ModuleType("module with ' quote"), "attribute with ' quote")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'module with ' quote' has no attribute 'attribute with ' quote'
>>> 

so they should all be:

AttributeError(f"module '{__name__}' has no attribute '{name}'")

The error message text is changed. While the text is not a part of stable API and can be wildly changed, we usually don't do it in bugfix releases without a strong reason.
That's why I don't want to backport the PR.
