remove comments for online validators

[rbavery]

Description

This removes comments so that the schema passes stricter jsonschema requirements that are common in online jsonschema validators. I think this is a non breaking change since it doesn't affect python validation. I would prefer to keep comments in but would rather be able to see errors neatly presented in online validators.

I did the quick thing in just removing all comments but probably some of these comments can be kept if they don't break jsonschema validation.
