Bookmark Feature

**Description:**
We're planning to add a "Bookmark" feature to our React web application, allowing users to save specific parts of the text. This feature will enhance the user experience by enabling them to mark and revisit important sections of content.

**Implementation Details:**

1)Users will have the ability to select and bookmark specific sections of text.
2)Bookmarked sections will be easily accessible for future reference.
3)We aim to create a user-friendly interface for adding, managing, and accessing bookmarks.
