Audit all plugins on our jenkins server

[sxa]

Follow-on to the work done in #2108:
We have been using the current jenkins server for some time and we should look at all the plugins that we have in order to ensure the following:

• Anything we rely on is being kept patched from a security perspective (i.e. has some sort of maintainer)
• Everything we have installed is understood and we have a record of what it is needed and used for
• Ensure that we can recreate the server from scratch if required with the plugins we need.
  As a starting point for some that are required, the ones used in our private jenkins server are listed at https://github.com/eclipse-cbi/jiro/blob/master/instances/adoptium.temurin-compliance/target/jenkins/plugins-list.txt and should be a subset of the ones we have on the public server.
