Improve DEBUG CONSOLE for program input

[testforstephen]

In Java Debug, we found user often uses the DEBUG CONSOLE for program input by mistake. I guess it's because other IDEs like eclipse/intellij both support in-place text input in CONSOLE. Is it possible to improve the DEBUG CONSOLE behavior? Or at least improve the user awareness.

I understand that it can be confused. Suggestions are welcome on how to improve this.
We could put a placeholder text in the debug console input which could inform the user that this input is for the read - evaluate loop.

@testforstephen you could make VS Code's "integrated terminal" the default for Java because a REPL is not that important for Java, correct?

[testforstephen]

lots of Java users are using evaluate feature correctly, not sure how much REPL counts. Changing the default console to "integrated terminal" feels a little aggressive.

Another helpful tip is support comments when generate initial debug config.

        {
            "type": "java",
            "name": "Debug (Launch)",
            "request": "launch",
            "cwd": "${workspaceFolder}",
            // To support console input, please switch console to integratedTerminal or externalTerminal.
            // "console": "integratedTerminal",
            "console": "internalConsole",
            "stopOnEntry": false,
            "mainClass": "",
            "args": ""
        },
