Updating Jenkins version

[ggsun]

I tried to update Jenkins to the latest LTS version since the version we were using had some non-critical UI errors (https://issues.jenkins.io/browse/JENKINS-69627) that were preventing me from easily giving administrator privileges to new accounts. The newer versions of Jenkins does not support Java 8 (which is the default version of Java on Sherlock) so I had to edit the shell script we use to fire up a Jenkins task /home/groups/mcovert/usr/local/bin/jenkins_job.sh to load modules for newer versions of Java (11 or 17). Running Jenkins with the new Java versions led to this reported error (https://stackoverflow.com/questions/68490185/trying-to-install-startup-jenkins-in-ubuntu-server-hudson-util-awtproblem) which I wasn't able to resolve on Sherlock. I tried installing fontconfig to $GROUP_HOME but this did not resolve the issue. I ended up updating Jenkins to the latest version that supports Java 8 instead (2.346.1), which still has the same UI errors.

I was be able to use a workaround to add @rjuenemann as an admin, so I don't think this is something that we'll need to resolve urgently. Though we might need to eventually update Jenkins as things get deprecated and more issues arise.

Thank you for promoting me to admin! I appreciate you documenting this and for your hard work on trying to resolve the issues.
