Description

Issue - #3062

Updated the code to optionally pass custom validate_error_message while making Prompt, IntPrompt, FloatPrompt and Confirm ask method.

Example

    answer = Confirm.ask(
        "continue",
        console=console,
        stream=io.StringIO(INPUT),
        default=True,
        validate_error_message="[prompt.invalid]Per favore digita S o N",
    )

    validate_error_message = "Invalid Integer. Enter a valid integer"
    number = IntPrompt.ask(
        "Enter a number",
        console=console,
        stream=io.StringIO(INPUT),
        validate_error_message=validate_error_message,
    )
