Update to latest specs.

The ONDC has made a few updates with new mandatory fields. Please update the package to adapt the latest specs

PS: I have tried to fix the issue myself but could not because OpenAPI - Typescript generators getting failed. How did you manage to generate types.ts from the specs?

Dear @abdulllrashid I used the same types.ts file from the ondc repo for this.
Feel free to create a PR for the updates
