DSC error short description should not include warnings

[mdanish-kh]

Description of the new feature / enhancement

When a DSC operation fails, the error notification contains too much verbose information, in particular the DSC warnings as well. The description of the error should not include warnings from DSC output

Steps to reproduce

1. Go to validate a resource page
2. Enter Microsoft.WinGet/Package and click Get operation
3. The operation fails as no ID is provided, but the UI notification is too noisy to appropriately communicate this to the user

Actual Behavior

Expected Behavior

We should have a parser for DSC output which is currently a string result and separate warnings from errors

I chatted offline with @JohnMcPMS about this. Right now, the WinGet Configuration COM API just returns the raw output from the DSC process as a string. We were wondering if WinGet could instead expose that output as JSONLines, or maybe the COM API could parse those JSONLines and return objects or strings.
