spring-boot-micrometer-tracing-opentelemetry fails if spring-boot-opentelemetry isn't there #48585
Description
Those dependencies in a Boot 4.0.x app:
implementation 'org.springframework.boot:spring-boot-micrometer-tracing-opentelemetry'
implementation 'io.micrometer:micrometer-tracing-bridge-otel'
lead to this failure:

Description:
Parameter 0 of method otelTracer in org.springframework.boot.micrometer.tracing.opentelemetry.autoconfigure.OpenTelemetryTracingAutoConfiguration required a bean of type 'io.opentelemetry.api.OpenTelemetry' that could not be found.
Action:
Consider defining a bean of type 'io.opentelemetry.api.OpenTelemetry' in your configuration.
I guess we either have to add a dependency from spring-boot-micrometer-tracing-opentelemetry to spring-boot-opentelemetry or add some @ConditionalOnBean.
