upgrade(jsonschema): jsonschema==3.2.0 (#19765)

We need this for Py 3.6+ compatibility. The changelog for the project itself doesn't report any breaking changes for Python side. The main change is making [draft 7](json-schema.org/draft-07) the default which states that it is fully backward-compoatible with draft 6, the current default:

>For the Core and Validation specifications, draft-07 is a relatively minor update. In terms of validation keywords and outcomes, it is fully backwards-compatible with draft-06.

At the end of [Validating Formats](https://python-jsonschema.readthedocs.io/en/stable/validate/#validating-formats), we have the following note:

> Certain checkers will only be available if an appropriate package is available for use. The easiest way to ensure you have what is needed is to install jsonschema using the format or format_nongpl setuptools extra – i.e.
>
>$ pip install jsonschema[format]
>
>which will install all of the below dependencies for all formats.
>
>Or if you want to install MIT-license compatible dependencies only:
>
>$ pip install jsonschema[format_nongpl]
>
>The non-GPL extra is intended to not install any direct dependencies that are GPL (but that of course end-users should do their own verification). At the moment, it supports all the available checkers except for iri and iri-reference.

>*If the following packages are not installed when using a checker that requires it, validation will succeed without throwing an error, as specified by the JSON Schema specification.*

Hence, our failed test on the first try. Glad we had a test for this.
