[docs] [issue8925] Improve c-api/arg.rst: use "bytes" or "str" types instead of "string"

[Georg Brandl]

Georg Brandl <georg at python.org> added the comment:

The glossary (see docs.python.org/glossary) does not have an entry for "buffer interface" or "buffer protocol".  An index entry just means that some location in the code defines this entry and gets a link back.

Of course, you can also link to the C API section using :ref:`bufferobjects`.
