[Draft] Add JSON Schema Test Suite to CI

[hudson-ai]

First attempt at getting the test suite running in CI. I don't really know how to effectively use github CI, so this is a bit of an experiment.

Note that this steals some code from a few existing scripts (namely sample_parser/src/json_schema_testsuite.rs).

TODOS:

• commit some baseline version of the artifact for regression analysis
• compare against baseline with helpful presentation of differences
• build some process for bumping the baseline (probably just run a script and update committed baseline)

You could just add it to the test-guidance.sh script (which we probably want to rename to build-and-test.sh or testall.sh or something). This way there is just one script to run to check if things still work locally. I guess running this suite takes a few seconds at most?

Sounds good, and yeah it's under a second :)
