Fixed bug: Do not use Array index in keys

[ajay-dhangar]

To avoid using the array index as a key, you can use a unique value from the tag array. Here is a revised version of the relevant code snippet:

<span key={tag} className="lesson-tag">{tag}</span>

This ensures that each span element has a unique key, which is important for React's rendering logic.
