The code in ApiQuerySiteInfo::appendAutoCreateTempUser may also need an update as it returns the matchPattern in an API response.

This makes sense as a generic capability (maybe we'll want to change username patterns agains when temp users are already in production) but for the specific problem, I don't think anyone would miss those temp users on Beta if they were gone (turned into normal users, I guess?).

These would essentially become normal users. However, if the user_is_temp column is ever used then we would have an inconsistency (as the DB flags the users as temporary but the matching patterns says not) unless we updated the DB or updated the code to read the status from the DB instead of matching to patterns.

@Dreamy_Jazz As seen from the screenshots below, they do support both temp account formats. This will be moved to Done. Thanks for all your work!
