feat: Implement category filters for artwork gallery

[SinghCod3r]

This PR introduces a new feature that allows users to filter artworks by category.

Key changes include:

• Added a category filter bar to index.html with radio buttons for "All", "Abstract", "Funny", "Minimal", and "Animated" categories.
• Updated arts.json to include a category field for each artwork, programmatically assigned based on keywords in titles and filenames.
• Modified style.css to style the category filter bar and implement CSS-based filtering logic with smooth transitions.
• Updated script.js to dynamically add data-category attributes to artwork cards and implement JavaScript-based filtering when radio buttons are selected.

These changes enhance the user experience by providing an organized way to browse artworks based on their categories.

Closes #264

On what aspect you are categorizing the arts into different categories ?
Can you please provide the logic of how the arts are categorized.

One thing can be done in arts.json we have to add one more field in each of the arts about its categories.
But this method will take too much time and if we try to give categories with AI it will give random on the basis of their name which is not optimal.

So @SinghCod3r tell your strategy
