new FastAPI lifespan might not work in lambda

	if "AWS_EXECUTION_ENV" in os.environ:
	loop = asyncio.get_event_loop()
	loop.run_until_complete(app.router.startup())

previously we were checking if we were in AWS Lambda to run the startup event but with the new lifespan method implemented in latest FastAPI (and used in tipg https://github.com/developmentseed/tipg/blob/main/tipg/main.py#L32-L59) we might have the same issue

I confirmed this. There is no more app.router.startup for the tipg application 🤦
