Is numpydoc_use_blockquotes deprecated or not yet?
On the documentation website for version 1.5.dev0: https://numpydoc.readthedocs.io/en/latest/install.html#configuration

>     If your styling requires blockquotes, switch this config option to True.

And we are on version 1.4/1.5, so does this key still exists?
Could you update the configuration documentation? 🙏
