Support for Splitting Input String into Multiple Arguments in launch.json

Description

Currently, VS Code's launch.json configuration does not natively support splitting a single input string into multiple arguments for the args array when launching a Python script. This limitation makes it difficult to pass multiple arguments to a script from a single input prompt.

Steps to Reproduce

0. example app

import typer

app = typer.Typer()

@app.command()
def command1(arg1: str):
    typer.echo(f"Argument 1: {arg1}")

@app.command()
def command1(arg1: str, arg2: str, arg3: str):
    typer.echo(f"Argument 1: {arg1}")
    typer.echo(f"Argument 2: {arg2}")
    typer.echo(f"Argument 3: {arg3}")

if __name__ == "__main__":
    app()

1. Create a .vscode/launch.json file with the following configuration:

   {
     "version": "0.2.0",
     "configurations": [
       {
         "name": "Run CLI Script",
         "type": "debugpy",
         "request": "launch",
         "program": "cli.main",
         "args": [
           "${input:args}"
         ],
         "console": "integratedTerminal"
       }
     ],
     "inputs": [
       {
         "id": "args",
         "type": "promptString",
         "description": "Enter the args for the task",
         "default": "previous_args"
       }
     ]
   }

2. When running the above configuration, enter multiple arguments as a single string (e.g., command1 arg1).

3. Observe that the entire string is passed as a single argument rather than being split into individual arguments.

Expected Behavior

It would be beneficial if launch.json could natively support splitting a single input string into multiple arguments for the args array. For example, when entering arg1 arg2 "arg with spaces" arg4, the arguments should be passed as arg1, arg2, arg with spaces, and arg4 to the script.

Additionally it would be nice to have the default value be dynamic such that you could reuse the latest used args as the default value.

### Tasks

This would basically be an input that would return multiple values, which is a different type of thing than the existing promptString.

Yes, Would be nice to have one input field that takes in any amount of args, (and then uses the previously ran args as default for the next run).
