Add a link to GitHub issues (vibe-kanban) (#172)

* Perfect! I've successfully added a GitHub issues link next to the existing docs link in the navigation bar. The changes include:

1. **Added `MessageCircleQuestion` icon import** from lucide-react
2. **Added a "Support" button** that links to `https://github.com/BloopAI/vibe-kanban/issues`
3. **Added proper spacing** between the buttons with `space-x-1`

The support link will now appear in the top navigation bar next to the "Docs" button, making it easily accessible for users who need help or want to report issues.

* prettier
