[Inference Providers] feat. Refactor the NovitaTextToVideoTask using the async API.

[viktor2077]

This PR refactors the NovitaTextToVideoTask using the async API, aiming to allow inference with models that may take over 2 minutes to generate results.

Hey there - thank you for your contribution!

I have left a few comments and suggestions about typing and code style

Excited to see Novita's text-to-video service on the platform!

No need for casting if you use the proper type here
Also, params.args.parameters can be undefined

Suggested change

	override preparePayload(params: BodyParams): Record<string, unknown> {
	const { num_inference_steps, ...restParameters } = params.args.parameters as Record<string, unknown>;
	return {
	...omit(params.args, ["inputs", "parameters"]),
	...(params.args.parameters as Record<string, unknown>),
	...restParameters,
	steps: num_inference_steps,
	prompt: params.args.inputs,
	};
	}
	override preparePayload(params: BodyParams<TextToVideoArgs>): Record<string, unknown> {
	const { num_inference_steps, ...restParameters } = params.args.parameters ?? {};
	return {
	...omit(params.args, ["inputs", "parameters"]),
	...restParameters,
	steps: num_inference_steps,
	prompt: params.args.inputs,
	};
	}

Hi @SBrandeis, thanks for this suggestion. And I will encounter the following error if I don't cast the type explicitly:

Property 'num_inference_steps' does not exist on type '{}'.ts(2339)

[viktor2077]

and I'm refactoring the code to handle cases where params.args.parameters is null or undefined by using an empty object {} as the default value. This ensures the destructuring operation won't fail even if the parameters property doesn't exist:

const { num_inference_steps, ...restParameters } = (params.args.parameters as Record<string, unknown>) ?? {};

Thanks @SBrandeis , these suggestions are detailed and helpful!
