Add Dark Mode Support on Website

[JsExpertCoder]

The Inertia.js website is currently optimized for light mode, which can be straining on the eyes, especially for users who prefer or require dark mode for better readability and reduced eye strain. Adding dark mode support would improve the accessibility and user experience of the website.

Benefits:

• Improved accessibility for users who prefer dark mode.
• Enhanced user experience, especially for developers who often work in low-light environments.
• Modernizes the website to align with current design trends.
