Prefer older version of jsonschema without Rust dependency

[t1m0thyj]

What It Does

Partially addresses #388.

jsonschema 4.18.0 replaced a pure C dep with a Rust-based one that is uninstallable on z/OS - see python-jsonschema/jsonschema#1117.

Downgrading jsonschema to 4.17.3 resolves the dependency issue, but is not supported in Py3.14 and above.

Until we have time in the future to investigate a replacement for jsonschema, the best solution seems to be making the jsonschema version conditional based on Python version, and documenting that Py3.14 is not supported on z/OS.
