Update args type

Related to microsoft/debugpy#1004.

[int19h]

The new type for "args" isn't just string: it's either an array of strings (as it used to be), or a single string. If it is a single string, then no escaping is performed, and thus one can use shell variable substitution via $, output redirection via > etc. This is the mode that's not supported for "internalConsole" (because there's no shell there) - array "args" is supported everywhere.

@roblourens Any recommendation here on how to set the type to be both string or array?

[roblourens]

"type" can be an array, here's how it looks in js-debug:

"args": {
  "default": [],
  "description": "%node.launch.args.description%",
  "items": {
    "type": "string"
  },
  "type": [
    "array",
    "string"
  ]
},

Suggested change

	"default": "",
	"description": "Command line arguments passed to the program. (not supported for `internalConsole`)",
	"default": [],
	"description": "Command line arguments passed to the program.",

@int19h We don't need to say that it is not supported in internal console, right? and the default should still be [].

[int19h]

"args" in general is supported, only the no-array version isn't. I think this is enough of a corner case to not bother mentioning in the docstring.
