feat(AI Transform Node): New node

[michael-radency]

Summary

fix to original PR #9990

AI_TRANSFORM_NODE_TYPE has to be added to SCRIPTING_NODE_TYPES and NODES_WITH_RENAMABLE_CONTENT; otherwise, the original items are updated.

---

This PR introduces a new "AI Transform"* node that generates code snippets based on user instructions. The AI is context-aware, understanding the workflow's nodes and their data types. Users can simply enter their instructions and click the "Generate Code" button to let the AI automatically populate the Code parameter.

---

During development, the node's "button" property was improved:

export type NodePropertyAction = {
	type: 'askAiCodeGeneration';
	handler?: string;
	target?: string;
};

export interface INodePropertyTypeOptions {
	
	buttonConfig?: {
		action?: string | NodePropertyAction;
		label?: string; 
		hasInputField?: boolean;
		inputFieldMaxLength?: number; 
	};
	...
}

This updated interface allows you to specify a label, an optional input field with its maximum input length, and an action. The action can be specified as a string or as a NodePropertyAction, which allows you to set the type of action (currently only 'askAiCodeGeneration') and optionally an action target, such as a parameter that would be affected as a result of this action. Additionally, a handler function defined in methods.actionHandler can be executed on the backend when clicked.

	methods = {
		actionHandler: {
			async generateCode(this: ILoadOptionsFunctions, payload: IDataObject | string | undefined) {
				const url = this.getNodeParameter('url', 0) as string;
				let body: IDataObject = {};
				if (payload) {
					body = typeof payload === 'string' ? jsonParse(payload) : payload;
				}
				const response = (await this.helpers.httpRequest({
					method: 'POST',
					url,
					headers: {
						'Content-Type': 'application/json',
					},
					body,
				})) as {
					data: { code: string };
				};

				return response?.data?.code;
			},
		},
	};
