After T350133 was deployed, namespaceDupes.php was NOT run on the maintenance server.
Because of recent issues with the namespaceDupes script tracked in T350443, we should wait to run the script until after the limits on write queries has been implemented.
See https://wikitech.wikimedia.org/wiki/Adding_Namespaces
Acceptance Criteria
- run mwscript maintenance/namespaceDupes.php --wiki=bnwiki --fix once T350443 is fixed
