Support for Airflow 3

[BasPH]

Airflow 3 is still some time out, but Starship is currently limited to Airflow 2 only:

starship/astronomer_starship/compat/starship_compatability.py

Lines 1225 to 1242 in b854d53

	if int(minor) == 10:

	if int(minor) == 0:
	return StarshipAirflow20()
	return StarshipAirflow()
	else:
	raise RuntimeError(f"Unsupported Airflow Version: {airflow_version}")

Running Starship on Airflow 3 raises this exception:

RuntimeError: Unsupported Airflow Version: 3.0.0.dev0

Created this issue as a roadmap item.
