Suggestion: deprecate "rech.cobol.debug.params" in favor of vscode standard (and adjust the docs)

[GitMensch]

The current way is the following launch configuration (at least as I've understood the docs):

{
	"version": "0.2.0",
	"configurations": [
		{
			"type": "COBOL",
			"request": "launch",
			"name": "COBOL Debugger",
			"commandLine": "isdbg.exe $1 $2",
			"params": [
			    "Program name",
			    "Sample question for second parameter",
			],
			"stopOnEntry": true
		}
	]
}

The vscode default is to use configurable input parameters instead (those also allow drop-downs, get parameter from a command, ... via its types, see Input Variables docs), which would look like the following (and comes "for free" - the only thing to do would be deprecation of rech.cobol.debug.params and removing when possible):

{
	"version": "0.2.0",
	"configurations": [
		{
			"type": "COBOL",
			"request": "launch",
			"name": "COBOL Debugger",
			"commandLine": "isdbg.exe ${input:prog} ${input:second}",
			"stopOnEntry": true
		}
	],
	"inputs": [
		{
			"id": "program",
			"description": "Program name",
			"type":  "promptString",
			"default": "YourMain"
		},
		{
			"id": "second",
			"description": "Sample question for second parameter",
			"type":  "promptString",
			"default": ""
		}
	]
}
