fix: replace assert JSON imports with createRequire for compatibility

[Tsaihemanth150]

This pull request fixes a compatibility issue with JSON imports in ES modules.
Previously, the project used the following pattern to import .json files:

import data from "./file.json" assert { type: "json" };
While this works in some versions of Node.js with experimental flags, it often fails with the error:

SyntaxError: Unexpected identifier 'assert'
To ensure consistent behavior across environments, all such imports were replaced with:

import { createRequire } from "module";
const require = createRequire(import.meta.url);
const data = require("./file.json");
This approach:

Avoids the need for --experimental-json-modules flag.

Works reliably in ES module projects.

Fixes crashes during app startup (seen in yarn start).

Enhances developer experience and avoids platform-specific behavior.

✅ Changes Made
Replaced all import ... assert { type: "json" } with createRequire()-based imports.

Applied changes across all JSON import files (e.g., books.json, cats.json, status-codes.json, etc.).

Ensured consistent structure with a single createRequire declaration per file.

🧪 Tested
Verified that yarn start runs successfully without crashing.

Confirmed that all JSON data loads correctly and behaves as expected.
