Borrow Module | View Borrows By Book Feature

# View Borrow Process [By Book]

### User Story
As a librarian, I want to be able to view a list of all the users who have borrowed a specific book from the library. The system should provide me with a list that includes details about each user, such as their names and borrowing dates. This way, I can monitor the usage of individual books in the library's collection.
