Update Generate prompt for leonardo

[AliLee0923]

• Created a function for generating detailed image prompts based on an array of words using the OpenAI gpt-3.5-turbo-instruct model. It creates a pictogram-style description for each word, determining whether the word represents an ACTION or OBJECT, and formats the prompt accordingly. (generatePromptForImageGeneration)
• Created another function for combining the functionality of generating word suggestions and prompts for Leonardo AI. It fetches suggestions based on a given prompt, processes them into a list of detailed image prompts, and returns the results. (getPromptsForLenonardo)
• Created a function for generating a detailed image prompt for a single word using the OpenAI API. This is a simplified and focused version of generatePromptForImageGeneration, handling only one word at a time. (generateAPromptForLeonardo)
