Remove smart quotes from all docstrings.

[bdice]

Description

This PR removes all "smart quotes" from the library by enforcing a pre-commit hook.

Smart quotes typically arise from copying rendered docstrings from Pandas, because Sphinx automatically transforms straight quotes into smart quotes when rendering the docs as HTML. However, the use of smart quotes is undesirable in code, and makes it difficult to do find-replace transformations if straight and smart quotes are mixed.

I have made suggestions to fix this several times before, so I am making the suggestions more permanent and automatically enforceable via a pre-commit style check:

• [REVIEW] Reduce/Remove reliance on **kwargs and *args in IO readers & writers #12025 (comment)
• Implement DataFrame diff() #9817 (comment)
• Implement Series.datetime.floor  #9571 (comment)
