Steps to reproduce:
1 - Start the portal
2 - Add a wiki portlet
3 - Add content to the front page
4 - Wait for a couple of minutes (the time when the page was updated only shows minutes, so you'll need to wait at least 1 minute to see the difference)
5 - Update the front page a couple of times (once is enough tbh)
6 - Click on "Details"
Observed behavior: "Last updated by" and "Created By" is the same, showing the user who created the page
Expected behavior: "Created by" should show the user and time when the wiki article was created, "Last updated by" should show the user and time when the wiki was last updated.
