CheckUser: Hide temp accounts onboarding dialog by default
Why:
- The CheckUser extension implements a onboarding dialog for temporary accounts that is shown to users with rights to reveal their IPs
- This can be annoying for test wikis, as the user does not need to be informed how to use the tools
- Hiding the dialog by default on patch demo wikis avoids the issue, while still allowing testing the dialog at a later time
What:
- Set
$wgDefaultUserOptions['checkuser-temporary-accounts-onboarding-dialog-seen'] = 1;
in for the LocalSettings file for CheckUser.
