Sleuth not working with Spring Boot 3.0.0 #2239
Description
Describe the bug
I have a Spring Boot 3.0.0 based application where I tried to integrate Spring Sleuth with Spring Kafka - unfortunately without much success. In simulating that issue I've came up with a minimal example that's basically based on the Spring Sleuth Getting Started section. The resulting application doesn't generate traces/spans and doesn't log 'em as described in the docs.
I'm also not able to inject instances of Tracer into my Beans (as described here) since there is apparently no bean of that type configured:

***************************
APPLICATION FAILED TO START
***************************
Description:
Field tracer in de.bender.sleuth.sleuthdemo.SleuthController required a bean of type 'org.springframework.cloud.sleuth.Tracer' that could not be found.
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'org.springframework.cloud.sleuth.Tracer' in your configuration.Notice: When changing the version of spring-boot-starter-parent from 3.0.0 to i.e. 2.6.6 the same example produces:
Sample
I've added the sample-project that produces the output from above. Just change the version of spring-boot-starter-parent from 3.0.0 to 2.6.6 to simulate my output.
