Added dark mode toggle and functionality to the info page

[gbengaoluwadahunsi]

Motivation I have created this Pull Request to enhance the user experience of the website by implementing a dark mode feature on the info.html page. This improvement aligns with the current trend of offering users customizable themes for better accessibility and personalization.

Testing I have thoroughly tested this implementation beyond the automatic hooks. The testing involved:

Verifying the functionality of the dark mode toggle button. Ensuring proper styling and contrast for readability in dark mode. Testing compatibility across different browsers and devices. Checking for any potential conflicts with existing features.
