Fixing Javadoc for fixing the pipeline

[twasyl]

Working on #153, the pipeline failed due to some incorrect Javadoc syntax. Just trying to fix that so the pipeline is green on the step.

• 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

Thanks for this PR. The closing </p> are implied in most scenarios and aren't the source of errors. Note, you saw an error when you had <p><ul></ul></p> because the <ul> implicitly adds </p> before it.
