Description

This PR introduces a Partial Title Search functionality for books. Previously, users could only fetch books by their exact name using getBookByName. This enhancement allows users to find books even if they only know a fragment of the title, with support for case-insensitivity.

Summary of changes:

BookRepository
Added a new query method findByNameContainingIgnoreCase(String name) to leverage Spring Data JPA's derived query feature.

schema.graphqls
Introduced the searchBooks(title: String!): [Book] query to the GraphQL schema.

BookController
Implemented the @QueryMapping for searchBooks to connect the GraphQL entry point with the repository logic.
Fixes keploy/keploy#3888

How Has This Been Tested?

The changes were verified manually using curl against the local GraphQL endpoint.

Test Case: Partial and Case-Insensitive Search

Setup: Ensure at least one book exists, e.g., "The Great Gatsby".
Execution: Run the following curl command:
bash
curl -X POST http://localhost:8081/graphql
-H "Content-Type: application/json"
-d '{"query": "{ searchBooks(title: "great") { name author { firstName lastName } } }"}'
Expected Result: The API returns an array containing "The Great Gatsby", even though the search term "great" was lowercase.

Additional Context (Please include any Screenshots/gifs if relevant)

This feature improves the discoverability of books in the library system and provides a more user-friendly search experience compared to exact matching.
