test(coverage): omit pure typing module commitizen/question.py

commitizen/question.py defines TypedDicts, Literal aliases, and a union type used purely for static typing. It has no runtime code paths to exercise, so excluding it from the coverage report removes a misleading 0% line and reflects its purpose more accurately.

Closes #1904
