Adding IDE configuration and debugging configuration for VulnerableApp-php

[preetkaran20]

As VulnerableApp-php is in initial phase and hence we are using VSCode as IDE for the project, we do the code changes and then use docker to test the code changes.
As this is quite a tedious task where there is no way to debug the code except the very basic echo statements.

Solutions

1. We are looking for an IDE setup for the project such that we can debug the code changes without deployments.
2. Clear set of instructions for IDE setup.
