Deprecation notice in docs for Catalog.get_all_items() includes extra parentheses

[Tyler Erickson]

In the pystac docs the docs for Catalog.get_all_items() have an extra set of parentheses in the deprecation notice.

The docstring for the method looks ok though, so I am not sure what is going on...

pystac/pystac/catalog.py

Line 603 in b3edc53

             Use :meth:`pystac.Catalog.get_items(recursive=True)` instead.

Thanks for reporting! My bet is that :meth: is doing something sneaky and adding the parens
