Address Archived Dependencies

What would you like to be added?

Priority 2: Address Archived Dependencies

• Replace github.com/opentracing/opentracing-go — Medium risk. The OpenTracing project is archived and fully merged into OpenTelemetry. Migrate any remaining OpenTracing usage to OTel.

• Replace github.com/pkg/errors — Medium risk. Migrate to fmt.Errorf with %w. Etcd is using v0.8.1 (not even the latest archived version v0.9.1).

• Replace github.com/json-iterator/go — Medium risk. Evaluate whether standard encoding/json suffices or wait for Go 1.25's encoding/json/v2.

• Remove github.com/golang/mock — Already replaced by go.uber.org/mock in active code, but still in go.sum. Clean up the reference.

Sorry, I got to read the report this morning. Dims updated the report by my request (filtering out the tools submodules). github.com/pkg/errors was easy to address because it was only used in tools as an indirect dependency from github.com/grpc-ecosystem/go-grpc-middleware (#21295).
