DOC: [URGENT] Step to debug the app with Physical Device are incorrect in Onboarding.MD

[M4dhav]

Issue with current documentation:

In ONBOARDING.md the final step (Connecting Frontend and Backend) the step mentioned to connect and debug via a Physical Device is incorrect, i.e: the IP Address being used should be of the Laptop/Computer and not of the Phone.
