Use `callable` builtin to check for callables

This codemod fixes cases where hasattr is used to check if an object is a callable. You likely want to use callable instead. This is because using hasattr will return different results in some cases, such as when the class implements a __getattr__ method.

Our changes look something like this:

 class Test:

obj = Test()
- hasattr(obj, "__call__")
+ callable(obj)

If you have feedback on this codemod, please let us know!


Why is this codemod marked as Merge Without Review?

We believe this change is safe because using callable is a more reliable way to check if an object is a callable.
