feat(json): validate JSON schema via the jsonschema crate

Replace the todo!() json_schema::Validator stub with the jsonschema crate.

Errors are surfaced as 'property : message'; the message wording follows the
jsonschema crate and is *not* justinrainbow-compatible.

Port the ComposerSchemaTest and JsonFileTest schema cases to the new wording
(noted per test).
