Update argparse default argument format

[sondrelg]

Hi!

Thanks for creating this, I've only recently discovered it, but have adopted it all over the place - it's great!

I just enabled flake8 logging for something unrelated and found some warning logs related to this plugin. I just thought I would let you know 🙂

These are the errors:

flake8.options.manager    MainProcess    245 WARNING  option --pytest-fixture-no-parentheses: please update `help=` text to use %(default)s instead of %default -- this will be an error in the future
flake8.options.manager    MainProcess    245 WARNING  option --pytest-raises-require-match-for: please update `help=` text to use %(default)s instead of %default -- this will be an error in the future
flake8.options.manager    MainProcess    245 WARNING  option --pytest-parametrize-names-type: please update `help=` text to use %(default)s instead of %default -- this will be an error in the future
flake8.options.manager    MainProcess    245 WARNING  option --pytest-parametrize-values-type: please update `help=` text to use %(default)s instead of %default -- this will be an error in the future
flake8.options.manager    MainProcess    245 WARNING  option --pytest-parametrize-values-row-type: please update `help=` text to use %(default)s instead of %default -- this will be an error in the future
flake8.options.manager    MainProcess    245 WARNING  option --pytest-mark-no-parentheses: please update `help=` text to use %(default)s instead of %default -- this will be an error in the future

I've not really taken the time to check flake8 changelogs/code for more info.

If you wish to replicate, just run flake8 with -v 🙂
