Update Log4j 2 to 2.24.1

This also needs a test dependency on log4j-core because since version
2.24.0 if no provider implementation is found a no-op ThreadContextMap
is used, which causes test failures.

However, for normal usage that is probably not relevant since there the
user most likely will have some variant of Log4j provider, most likely
log4j-core as runtime dependency (but possibly also another provider).
