Update README with Enhanced Visual and Interactive Elements

[Lefatso]

This pull request updates the README file to improve its readability, visual appeal, and user interaction by incorporating icons and collapsible sections . Here are the key changes and reasons behind them:

Visual Enhancement with Icons:

Added icons for each programming language using skillicons.dev to make the README more visually appealing. Icons help users quickly identify their language of interest.

Interactive Collapsible Sections:

Converted the project lists under each programming language into collapsible sections. This makes the README more compact and easier to navigate, allowing users to expand only the sections they are interested in.

Simplified Table of Contents: Removed the traditional table of contents and replaced it with a visual representation of programming languages. Users can click on icons to jump to the detailed list of projects for that language, improving navigation efficiency. Consistent Layout:

Maintained a consistent format for each programming language section with an icon and project list. This consistency helps users know what to expect and find information quickly.

Benefits: Improved User Experience: The use of icons and collapsible sections makes the README more engaging and user-friendly. Efficient Navigation: Users can quickly find and access information relevant to their interests without scrolling through long lists.

Modern Look: The visual and interactive elements give the README a modern and professional appearance, enhancing the project's overall presentation.
