+- Remove the deprecated `go.opentelemetry.io/otel/bridge/opencensus.NewTracer`. (#4706)

 ## [1.20.0/0.43.0] 2023-11-10
 
 This release brings a breaking change for custom trace API implementations. Some interfaces (`TracerProvider`, `Tracer`, `Span`) now embed the `go.opentelemetry.io/otel/trace/embedded` types. Implementors need to update their implementations based on what they want the default behavior to be. See the "API Implementations" section of the [trace API] package documentation for more information about how to accomplish this.
