fix: Fix dependency security vulnerabilities

[its-ayush-07]

Description

Manually fixed the dependency vulnerabilities in all the folders(root, app, and api), without any breaking changes. I did it by updating the npm version to ^8.19.2 and, updating the versions of the vulnerable dependencies using the 'overrides' object in package.json.

Motivation and Context

Fixes #52

How Has This Been Tested?

Tested locally. The application is working fine.
