Update minimum pre-commit version to 2.9.2

The PR which led to 2.9.0 was made by a data scientist and so it contains a bug in the default types for `types_or`, it'd be better to have 2.9.2 as the minimum version - at least, that's what Anthony Sottile suggested be done in `black` psf/black#1875 (comment)
