Add a button to go from app.graphite.com to github.com
Dies sind alle Versionen des Skriptes. Nur Versionen anzeigen, bei denen sich der Quelltext geändert hat.
If the toolbar already exists, add the button immediately
Run on document-idle, not document-start. This should help the button appear more reliably by waiting a bit longer for the page to load all elements.
- update styling to work in dark mode (steal styling from 'Review changes' button)
- match their new URL: app.graphite.com- update matching regex to handle dash (-) in repo or project name (thanks @gaosong2101!)
Fixes issue where the button might show twice
