 - Add `Values` method to `HeaderCarrier` to implement the new `ValuesGetter` interface in `go.opentelemetry.io/otel/propagation`. (#5973)
 - Update `Baggage` in `go.opentelemetry.io/otel/propagation` to retrieve multiple values for a key when the carrier implements `ValuesGetter`. (#5973)
 - Add `AssertEqual` function in `go.opentelemetry.io/otel/log/logtest`. (#6662)
