[Course Pacing] Change "submit the assignment" to "submit the quiz" on Module completion requirements

[adamboyce]

When adding Module completion requirements for a quiz, the options are confusing. Why does it say "submit the assignment" if we are creating a requirement for a quiz?

Or is there some reason the code is the same checking for submissions regardless of assignment or quiz? If so, would a more generic option be better? "submit the item" or just "submit" ... Neither of those are ideal, but you get the idea.
