Data node ships with old log4j memory log appender

[mpfz0r]

I've installed the data node using the debian package

In the logs I see this warning:

Apr 11 11:31:01 bookworm graylog-datanode[7276]: 2024-04-11T11:31:01.071279126Z main ERROR Deprecated log4j.xml setting detected <bufferSize="500"> Using default <bufferSizeBytes=50MB> instead

I'm not sure if we are even utilizing the in-memory logs in the data node.
But we should either fix or remove that line.

For Graylog we use
