Package is not compatible with python 3.11 due to changes in dataclass interface

[danielbjerk]

Describe the bug
Attempting to use gridapps.simulation with python 3.11 will result in ValueError due to Python 3.11 changing dataclass to be non-backwards compatible (see i.e. this discussion).
The ValueError is due to SimulationArgs, SimulationConfig, having class defaults (ModelCreationConfig and SimulationArgs, ApplicationConfig, TestConfig, respectively).

To Reproduce

$ mkdir tmp && cd tmp
$ py --version
Python 3.11.4
$ py -m venv .
$ py -m pip install gridappsd-python
$ py
>>> import gridappsd.simulation
Traceback (most recent call last):

    raise ValueError(f'mutable default {type(f.default)} for field '
ValueError: mutable default <class 'gridappsd.simulation.ModelCreationConfig'> for field model_creation_config is not allowed: use default_factory

Proposed solution
Use default_factory for these fields as well.

@dataclass
class SimulationArgs(ConfigBase):
    start_time: str = "1655321830"
    duration: str = "300"
    simulator: str = "GridLAB-D"
    timestep_frequency: str = "1000"
    timestep_increment: str = "1000"
    run_realtime: bool = True
    simulation_name: str = "ieee13nodeckt"
    power_flow_solver_method: str = "NR"
    model_creation_config: ModelCreationConfig = field(default_factory=lambda: __default_model_creation_config__)   # __default_model_creation_config__

and

@dataclass
class SimulationConfig(ConfigBase):
    power_system_config: PowerSystemConfig
    application_config: List[ApplicationConfig] = field(default_factory=list)
    simulation_config: SimulationArgs = field(default_factory=lambda: __default_simulation_args__)   # __default_simulation_args__
    service_configs: List[ServiceConfig] = field(default_factory=list)
    application_config: ApplicationConfig = field(default_factory=lambda: __default_application_config__)   # __default_application_config__
    test_config: TestConfig = field(default_factory=lambda: __default_test_config__)   # __default_test_config__

Elsewise, README and pyproject-dotfiles should be changed to reflect <3.11 requirement.

I can confirm this issue with python greater than 3.10. The suggested solution is will work however, i believe this would work as well:
field(default_factory=ModelCreationConfig)
field(default_factory=SimulationArgs)
field(default_factory=ApplicationConfig)
field(default_factory=TestConfig)
