Discord Command Arguments as List (#41113)

* start (i got distracted)

* feat: list-based arguments for the discord implementation

* chore: unnecessary?

* chore: rename ArgumentList to Arguments

* fix: rename error

* chore: todo

* fix: error, again. I'm silly.

* chore: review

* *sound of flames*
