refactor(ui): adjust hero section styling and content

Refactor the Hero component to improve visual spacing and update descriptive text for clarity.
- Adjusted `h1` margin-bottom and text color for better visual hierarchy.
- Updated the descriptive paragraph to be more concise and impactful.
- Modified the scroll indicator's bottom position for improved placement.
- Ensured `html` and `body` elements prevent horizontal overflow.
- Applied `max-w-full` to canvas elements to prevent layout issues.
- Updated `portfolio-data.json` to refine skill categories and add new skills (Python, Docker, Cloudflare).
