Draft 2019-09 split dependencies into dependentRequired and dependentSchemas, but neither is implemented, so both are silently ignored:

import fastjsonschema

schema = {
    '$schema': 'https://json-schema.org/draft/2019-09/schema',
    'dependentRequired': {'bar': ['foo']},
}
fastjsonschema.validate(schema, {'bar': 1})
# returns {'bar': 1}, should fail because foo is missing

Both keywords work like the two shapes dependencies already handles (a list of names, or a schema), so the draft 04 code moves into _generate_dependencies(rule) and the draft 2019 generator calls it for each keyword. The error rule is the keyword name. Like dependencies, they are inserted before properties so a default value can't trigger them. Drafts 04, 06 and 07 still ignore them. Schemas without $schema use the 2019 generator, so they get the new checks too.

dependentRequired.json and dependentSchemas.json from the test suite now pass, so I removed them from the draft 2019 ignore list. I also added a test in tests/test_object.py that a default doesn't trigger either keyword. The full suite passes and pylint is unchanged. CHANGELOG has an entry under UNRELEASED.

@horejsek same for this one, the workflows need approval before CI runs.
