[Doc]: --engine-use-ray is not documented

[hmellor]

📚 The doc issue

It looks like AsyncEngineArgs are not documented in https://docs.vllm.ai/en/latest/models/engine_args.html, meaning that --engine-use-ray is undocumented:

vllm/vllm/engine/arg_utils.py

Lines 441 to 464 in 563c1d7

	class AsyncEngineArgs(EngineArgs):
	"""Arguments for asynchronous vLLM engine."""

	@staticmethod
	def add_cli_args(
	parser: argparse.ArgumentParser) -> argparse.ArgumentParser:
	parser = EngineArgs.add_cli_args(parser)
	parser.add_argument('--engine-use-ray',
