A decorator that ensures all fields in a dataclass have default values
and that each field has a docstring.
If a `ConfigT` is used as a CLI argument itself, the `type` keyword argument
provided by `get_kwargs` will be
`pydantic.TypeAdapter(ConfigT).validate_json(cli_arg)` which treats the
`cli_arg` as a JSON string which gets validated by `pydantic`.
Config validation is performed by the tools/validate_config.py
script, which is invoked during the pre-commit checks.
