Improve "${command:pickArgs}" usage

[ClaudioCimarelli]

Slightly related to: microsoft/vscode-python#23003

There are two issues related to the variable "${command:pickArgs}" that could be improved.

1. "args": "${command:pickArgs}" does not work with console": "internalConsole"
2. "${command:pickArgs}" cannot be appended to a list of other args like this:

 "args": [
                "--args1",
                "value1",
                "--args2}",
                "value2",
                "${command:pickArgs}"
            ]
