Address failing test: test_runtime_backend_errors_handled

[asnare]

This PR addresses a failing test: test_runtime_backend_errors_handled

This test checks error-handling, but one of the scenarios started failing under CI/CD because the test assumed it couldn't do something. Environment permissions have been updated, which means that it could and the error wasn't triggered. This PR modifies the scenario so that it will always produce an error.

Resolves #489.

Incidental changes:

• Improve the identification of the parametrised tests.
• Upgrade Hatch from 1.9.4 to 1.16.5, without which the tests can't be run.
