Schema generation fails for CRD containing `oneOf` constraint

[eric-carlsson]

What happened?

When attempting to add a CRD dependency containing oneOf constraints, I got an error:

crossplane: error: failed to generate go code from OpenAPI schema: error generating type definitions: error 
generating code for type definitions: duplicate typename 'IoCiliumV2CiliumClusterwideNetworkPolicySpec0' 
detected, can't auto-rename, please use x-go-name to specify your own name for one of them

Upon stripping the corresponding oneOf constraints, schema generation works. The CRD contains other fields with similar constraints, so this doesn't affect all such constraints.

How can we reproduce it?

I received this error when attempting to add Cilium CRDs as a dependency:

crossplane dependency add https://github.com/cilium/cilium --git-ref=main --git-path=pkg/k8s/apis/cilium.io/client/crds

What environment did it happen in?

• Crossplane CLI version: v2.3.0
• Platform (e.g., linux/amd64): darwin/arm64
• Crossplane version (if applicable): N/A

I believe @haarchri has fixed this in the up version of the schema generator. We will port the fix to the open-source version (and eventually stop maintaining two versions 🙈).
