Add keywords to .desktop file
Summary:
FEATURE: 400989
The .desktop file for Spectacle doesn't have a "Keywords" entry. It would probably do well to provide Spectacle as a result when users search for 'Snipping Tool' as that's the Windows variant.
Test Plan: desktop-file-validate both before and after applying the patch
