chore: refactor read scheme to openapi from kubernetes api definition

Previously, only a single embedded Kubernetes API version could be specified, resulting in a lack of support for certain GVKs.
To address this, the goal is to create and utilize a unified scheme that consolidates Kubernetes API definitions.
As a preliminary step, the current method of loading API definitions will be improved.
