CAMEL-23498: Cleanup remaining SLF4J 1.x artifacts after upgrade to 2.0.x

[davsclaus]

Summary

• Replace log4j-slf4j-impl (SLF4J 1.x Log4j2 binding) with log4j-slf4j2-impl (SLF4J 2.x) in 9 component test dependencies and 2 exclusions
• Fix hardcoded jcl-over-slf4j version 1.7.36 in camel-launcher to use ${slf4j-version}

These are remnants missed during the SLF4J 1.7.x → 2.0.x upgrade (CAMEL-18932).

Modules updated (test dependency log4j-slf4j-impl → log4j-slf4j2-impl)

• camel-zeebe, camel-parquet-avro, camel-flowable, camel-optaplanner, camel-solr, camel-datasonnet, camel-swift, camel-camunda, camel-pulsar

Exclusions updated (stale artifact name)

• camel-milvus, camel-kudu

Version fix

• dsl/camel-jbang/camel-launcher/pom.xml: jcl-over-slf4j-version changed from 1.7.36 to ${slf4j-version}

Test plan

• Full reactor build passes (mvn clean install -DskipTests)
• CI build passes
