[pre-commit.ci] pre-commit autoupdate (#514)

* [pre-commit.ci] pre-commit autoupdate

updates:
- [github.com/python-jsonschema/check-jsonschema: 0.30.0 → 0.31.0](0.30.0...0.31.0)

* Set self-check of azure-pipelines to nonunicode

This is the only schema (to date) which provides an invalid regex
under unicode-mode evaluation. Tweak the metaschema check to agree
with it.
