Mw.wikibase.entity.lua bug fix instructions

Lua executing  or   caused problems with a big error message that says   and the page was added to   (or a local equivalent). This has now been fixed so we don't get new errors, but all affected pages still need need to be fixed.

To do this, you can do one of the following things to all pages in your local category and all pages you find when you search for   (because not all affected pages are in the error category!) in all namespaces:


 * Purge all pages
 * Use Pywikibot touch on all pages
 * Runt the script in T170039
 * Or rebuild any other way
