[debug] launch.json validation shows warnings for extension debug adapters

[daviwil]

A user reported this on the vscode-powershell repo:

PowerShell/vscode-powershell#20

When a user opens their launch.json to debug PowerShell scripts using my extension's debug adapter, they get a warning stating that the type is not an accepted value:

There's also a warning which states that a property named "request" is missing. These warnings cause the user to think that their launch.json file is configured incorrectly even though the debugger launches successfully.

I suppose the validation just hasn't been updated yet to account for non-node debug adapters?

In the future we will make the "request" field required so that warning is correct. Using "request" we distinguish if we should launch or attach.

As for the type not being an accepted value I made a PR in your repo to fix that.

Thanks for looking into this Isidor! Next time I'll check the docs to make sure I didn't do things wrong :)
