Heads up: Powershell snippet mixup variables with placeholders

[egamma]

The syntax has been been made stricter some time ago
https://code.visualstudio.com/docs/editor/userdefinedsnippets#_snippet-syntax and we are now emitting warnings.

@daviwil these are the warnings I get in the latest insiders

Thanks for letting me know! I've had reports recently (#767) of some of our snippet placeholders not working correctly, I'll fix those up in this week's release.

Oops. Some (most?) of those are my bad. Well, good that they are issue warnings now.

Fixed with PR #795.
