Implementation of query validation

[guptaashwanee]

Is your feature request related to a problem? Please describe.
req.query is not not validated now, in req.query.populate if wrong string is passed which is not available in the mongoose schema it gives error

StrictPopulateError: Cannot populate path null because it is not in your schema. Set the strictPopulate option to false to override.

Describe the solution you'd like
We should plan to implement validation library as zod.

Describe alternatives you've considered
Write now I have implemented a custom validation of req.query through zod.
