Cleanup canonical-data for clock
Cleanup canonical-data for clock

This PR does a cleanup of the canonical data of the `clock` exercise. It contains the following changes:

1. The word "Test" is removed from the test group descriptions, as that is superfluous (it is a test group description after all)
1. I've split the add and subtract test into separate groups. This makes things more sensible for test data generators.

I've bumped the PATCH version number, as I believe that according to the README, this qualifies as a patch version bump.
