Subject: [PATCH] Update translateToHuman.js

The improvements to the code include enhanced input validation, which clarifies the error message to indicate that both the query and API key are required. The API request payload has been separated into its own `payload` variable, improving readability. Error handling has been improved by adding a `try-catch` block to manage network or request errors more effectively. Descriptive error messages have been incorporated to aid in debugging, providing clearer information about issues encountered. Additionally, response handling has been refined with checks to ensure that `choices[0]` and `choices[0].text` exist before accessing them, and a default message is provided if no translation is available.
