Add possibility to "Group" commands

[definama]

It would be great to add the possibility to group commands (See extension "Run Terminal Command").

"command-runner.commands": [
{
"command": "mycommand1",
"name": "My Command Name 1",
"group": "GENERAL",
},
{
"command": "mycommand2",
"name": "My Command Name 2",
"group": "GENERAL",
},
{
"command": "mycommand3",
"name": "My Command Name 3",
"group": "PERSONAL",
},
{
"command": "mycommand4",
"name": "My Command Name 4",
"group": "PERSONAL",
},
]
