[Feature]: validate without calling the schema server

[csirmazbendeguz]

Problem Statement

I noticed that the ValidateRecord function calls the schema server:

oasf-sdk/pkg/validator/validation.go

Line 100 in e1739b7

resp, err := v.httpClient.Do(req)

My issue with this is now our tests in dir depend on the schema server because of this

Proposed Solution

I understand it's easier to implement it this way because there's less duplication. But would it be possible to implement the validation in the code instead?

Alternatives Considered

No response

Additional Context

I'm not saying this is a huge issue, but I think validation should be done without calling any external services. I was surprised to learn that's not the case
