[chore] Add "up" and "running" as stop words

[PierreBtz]

If an instance contains jobs named "up" and/or "running", those end up being anonymized, leading to a log entry like: Jenkins is fully item_outer_pub and item_square_life.

This is not really convenient when browsing through the logs and looking for "up and running".

With this change, the log entry becomes Jenkins is up and running.

More generally, and outside of the context of this PR, I wonder if some groups of words should not be automatically excluded, like two letter words, adverbs etc...

Testing done

Submitter checklist

• Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!
• Ensure that the pull request title represents the desired changelog entry
• Please describe what you did
• Link to relevant issues in GitHub or Jira
• Link to relevant pull requests, esp. upstream and downstream changes
• Ensure you have provided tests - that demonstrates feature works or fixes the issue

Yeah could be included as part of supporting regexps: https://issues.jenkins.io/browse/JENKINS-71841
