Update jsonschema requirement from ~=4.19.0 to ~=4.20.0

[dependabot]

Updates the requirements on jsonschema to permit the latest version.

Release notes

Sourced from jsonschema's releases.

v4.20.0

• Properly consider items (and properties) to be evaluated by unevaluatedItems (resp. unevaluatedProperties) when behind a $dynamicRef as specified by the 2020 and 2019 specifications.
• jsonschema.exceptions.ErrorTree.__setitem__ is now deprecated. More broadly, in general users of jsonschema should never be mutating objects owned by the library.

Changelog

Sourced from jsonschema's changelog.

v4.20.0

• Properly consider items (and properties) to be evaluated by unevaluatedItems (resp. unevaluatedProperties) when behind a $dynamicRef as specified by the 2020 and 2019 specifications.
• jsonschema.exceptions.ErrorTree.__setitem__ is now deprecated. More broadly, in general users of jsonschema should never be mutating objects owned by the library.

v4.19.2

• Fix the error message for additional items when used with heterogeneous arrays.
• Don't leak the additionalItems keyword into JSON Schema draft 2020-12, where it was replaced by items.

v4.19.1

• Single label hostnames are now properly considered valid according to the hostname format. This is the behavior specified by the relevant RFC (1123). IDN hostname behavior was already correct.

v4.19.0

• Importing the Validator protocol directly from the package root is deprecated. Import it from jsonschema.protocols.Validator instead.
• Automatic retrieval of remote references (which is still deprecated) now properly succeeds even if the retrieved resource does not declare which version of JSON Schema it uses. Such resources are assumed to be 2020-12 schemas. This more closely matches the pre-referencing library behavior.

v4.18.6

• Set a jsonschema specific user agent when automatically retrieving remote references (which is deprecated).

v4.18.5

• Declare support for Py3.12

v4.18.4

• Improve the hashability of wrapped referencing exceptions when they contain hashable data.

v4.18.3

• Properly preserve applicable_validators in extended validators. Specifically, validators extending early drafts where siblings of $ref were ignored will properly ignore siblings in the extended validator.
