* Improved documentation and message for the dcs_check_list_arguments unit test. (#78903)
## About The Pull Request
I've been contacted recently by san7890 regarding an opened issue report
about the aforementioned unit test. I've told them it's mainly an issue
about the lack of clarity and the bad choice of words in both
documentation and fail messages, and that I'd get to it soon.
I don't repute myself a good writer. The renewed doc and messages may
contain a few grammar issues, but I'm optimistic that it explains it way
more thoroughfully than before.
## Why It's Good For The Game
Better documentation for one of the few unit tests that might tell you
to "fix" stuff you're not directly responsible of. Suggestions are
welcome. This closes#78896.
## Changelog
N/A
* Improved documentation and message for the dcs_check_list_arguments unit test.
