Fix: Improve WelcomeView styling and readability (#7682)

* fix: improve WelcomeView styling and readability

- Reduced excessive padding from p-16 to p-6
- Removed excessive bold text throughout
- Made provider cards more compact with smaller icons (32x32px)
- Increased introduction text size from text-sm to text-base for better visibility
- Centered the main greeting title
- Improved visual hierarchy with proper text sizing and spacing
- Added subtle borders and improved color contrast

* fix: remove undefined color class from incentive text

Removed the text-vscode-warningForeground class as it wasn't defined in index.css. The incentive text now uses default color which looks good.
