normalize usage of terms 'argument' and 'parameter'

[Sergey Fedoseev]

​https://docs.python.org/3/faq/programming.html#faq-argument-vs-parameter (see for more detailed explanation)

What is the difference between arguments and parameters?
Parameters are defined by the names that appear in a function definition, whereas arguments are the values actually passed to a function when calling it.

Example of incorrect term usage: ​https://github.com/django/django/blob/6b3724fa1116c0949a6e0cd3e0dd55959a3abd93/docs/releases/2.0.txt#L75

I searched for argument in the docs directory.

Above example in the description should I change argument to parameter in other cases like these:

​https://github.com/django/django/blob/6b3724fa1116c0949a6e0cd3e0dd55959a3abd93/docs/internals/deprecation.txt

* The ``weak`` argument to ``django.dispatch.signals.Signal.disconnect()`` will
  be removed.

to

* The ``weak`` parameter of ``django.dispatch.signals.Signal.disconnect()`` will
  be removed.

---

* The ``host`` argument to ``assertsRedirects`` will be removed.

to

* The ``host`` parameter of ``assertsRedirects`` will be removed.

and similar ?

Oh, I see the pull request was abandoned? I can try to finish it up.

The pull request needs to be reviewed. If it looks fine, you can mark the ticket as "Ready for checkin".

Current PR is incomplete. Working on a new one that incorporates the changes made so far.

After looking at the large size of the patch, I don't think this is worth it. Changing so much documentation will require non-trivial work for translators and I don't think the current wording is causing any confusion. Practicality seems to trump purity here.
