various: comma fixes (exercism#2150)

* forth: reinstate seperate classes

The template removed seperate classes per major case, resulting in
several tests with duplicate names and therefore an incomplete test
suite.

This reinstates the distinct classes.

Fixes exercism#2148

* forth: minor black issue

Was accidentally running on a later version of Black than the one
specified in our requirements-generator.txt.

* various: fixes trailing comma issues

An upcoming change in Black revealed that we were adding unnecessary
trailing commas. These will _not_ be trimmed by Black in future builds.
