CAMEL-19713: Fix logging by ensuring use of SLF4J 2.0

[klease]

The org.wildfly.security:wildfly-elytron jar dependency of camel-elytron includes the SLF4J 1.x classes and there was a logback provider in the classpath.

Description

Target

• I checked that the commit is targeting the correct branch (note that Camel 3 uses camel-3.x, whereas Camel 4 uses the main branch)

Tracking

• If this is a large change, bug fix, or code improvement, I checked there is a JIRA issue filed for the change (usually before you start working on it).

Apache Camel coding standards and style

• I checked that each commit in the pull request has a meaningful subject line and body.

• I have run mvn clean install -DskipTests locally and I have committed all auto-generated changes
