EncodingWarning issued when PYTHONWARNDEFAULTENCODING=true

[jaraco]

When enabling PYTHONWARNDEFAULTENCODING, it triggers a warning in jsonschema (per PEP 597).

tests/test_scripts.py::TestNotebookDepsReader::test_one_code_block
  /Users/jaraco/code/jaraco/pip-run/.tox/py/lib/python3.11/site-packages/jsonschema/validators.py:109: EncodingWarning: 'encoding' argument not specified
    vocabulary = json.loads(path.read_text())

Probably that needs to be path.read_text(encoding='utf-8').

Thanks! Fixed (in another repo, as this code has moved for the next release which is already in beta.)

Appreciated.
