Add IntelliSense for CLI m365 commands ✍️

[Adam-it]

🎯Aim

the aim of this issue is to add IntelliSense for CLI for M365 commands so that VS code will suggest options (also optional) related to that command and if an option is a select type it should suggest correct values

Currently snippets add code only with obligatory params. I was thinking to add some kind of support for optional patametrs. For example a separate snippet for the same command with all optional params. Or, IMO better idea, add intelisense which will check what command is used anal suggest any kind of param for the command (obligatory or optional)
