This pull request updates the GitHub page in src/pages/GitHub.tsx to improve the visual design by replacing the GitHub icon with a custom logo and enhancing the text styling with animations and shadows.

Visual updates:

• Replaced the GitHubIcon component with a custom logo image (/icon.png) in the header. The new logo has a larger size (150x150px), a circular shape, and a gradient background for a more visually appealing design. [1] [2]

• Enhanced the title text styling by adding a glowing text shadow effect and a pulsing animation. This makes the title more dynamic and visually engaging.
