Zipkin Autoconfiguration is failing in actuator as readTimeout is deprecated in HttpComponentsClientHttpRequestFactory

I am using Spring boot 3.0.0-RC1 and using new micrometer Observability. When spring boot is trying to create a bean of type ZipkinRestTemplateSender here it couldn't create as readTimeOut is deprecated in HttpComponentsClientHttpRequestFactory

Below is the stacktrace

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'openTelemetry' defined in class path resource [org/springframework/boot/actuate/autoconfigure/tracing/OpenTelemetryAutoConfiguration.class]: Unsatisfied dependency expressed through method 'openTelemetry' parameter 0: Error creating bean with name 'otelSdkTracerProvider' defined in class path resource [org/springframework/boot/actuate/autoconfigure/tracing/OpenTelemetryAutoConfiguration.class]: Failed to instantiate [io.opentelemetry.sdk.trace.SdkTracerProvider]: Factory method 'otelSdkTracerProvider' threw exception with message: Error creating bean with name 'otelSpanProcessor' defined in class path resource [org/springframework/boot/actuate/autoconfigure/tracing/OpenTelemetryAutoConfiguration.class]: Failed to instantiate [io.opentelemetry.sdk.trace.SpanProcessor]: Factory method 'otelSpanProcessor' threw exception with message: Error creating bean with name 'zipkinSpanExporter' defined in class path resource [org/springframework/boot/actuate/autoconfigure/tracing/zipkin/ZipkinConfigurations$OpenTelemetryConfiguration.class]: Unsatisfied dependency expressed through method 'zipkinSpanExporter' parameter 1: Error creating bean with name 'restTemplateSender' defined in class path resource [org/springframework/boot/actuate/autoconfigure/tracing/zipkin/ZipkinConfigurations$RestTemplateSenderConfiguration.class]: Failed to instantiate [org.springframework.boot.actuate.autoconfigure.tracing.zipkin.ZipkinRestTemplateSender]: Factory method 'restTemplateSender' threw exception with message: Request factory class org.springframework.http.client.HttpComponentsClientHttpRequestFactory has the setReadTimeout method marked as deprecated

Exception is that this configuration shouldn't stop starting application.
