Restructure "Learn by Doing" section to display tutorial and "What You'll
Learn" side by side. Items now display vertically instead of in a 2x2 grid.
Changes:
- Tutorial positioned on left with flex: 1
- "What You'll Learn" section positioned on right
- Items arranged vertically using stack layout
- Increased container max-width from 900px to 1200px
- Responsive: stacks vertically on mobile, side-by-side on md+ screens
