add default value option for input dialog

[motty-mio2]

Hello
I like this library so much and use it for me personal projects thanks. This PR is similar to previous (#1563).

What

I add an option to set default value for input dialog

Usage

from prompt_toolkit.shortcuts import input_dialog


def main():
    result = input_dialog(
                title="Input dialog example", 
                text="Please type your name:", 
                default_text="George"
            ).run()

    print(f"Result = {result}")


if __name__ == "__main__":
    main()

Can you rename the parameter to default here?
For consistency with PromptSession: https://github.com/prompt-toolkit/python-prompt-toolkit/blob/master/src/prompt_toolkit/shortcuts/prompt.py#L899

I know for the radiolist_dialog, it's default_values, but I think there it can be more than one.
