jenkins: Investigate whether javaposse.jobdsl.plugin.ExecuteDslScripts needs to be retained

https://github.com/adoptium/infrastructure/issues/3491 the ExecuteDslScripts directory on the jenkins server needs to be kept. It takes just over 1MB of space and it generating one directory every few minutes.

The ones I've looked at seem to be related to job generation so I'm going to hand this over to @andrew-m-leonard and @smlambert - are you aware that these logs are being created and would you expect there to be generation activity this frequently? It would be good to understand
[javaposse.jobdsl.plugin.ExecuteDslScripts.xml.gz](https://github.com/adoptium/infrastructure/files/14873645/javaposse.jobdsl.plugin.ExecuteDslScripts.xml.gz)

Start with issue #3491 and inspect the attached javaposse.jobdsl.plugin.ExecuteDslScripts.xml.gz alongside the ExecuteDslScripts directory on the Jenkins server. Determine whether the recurring job-generation logs are expected and whether the directory must be retained; done means the retention decision and its operational rationale are recorded.
