This is technically a breaking change, so we need to make sure that this is needed indeed. I'll keep it in draft for now

I think this is a good fix.

Yes, this is definitely a bug. The correct URLs don't have "v" prefix, see the Schema Files directory: https://github.com/open-telemetry/opentelemetry-specification/tree/main/schemas

Since Schemas at OpenTelemetry are still Experimental we are free to make this breaking change (really a bug fix).
