Summary
Remove the autopromote mechanism currently in use for temporary-account-viewer, because we are migrating to a process of manually granting the right.
Background
As noted in T325451, we are no longer autopromoting users into temporary-account-viewer, in favor of manually assigning the right.
Technical notes
Remove the $wgAutopromoteOnce['onEdit']['temporary-account-viewer'] block in operations/mediawiki-config
Acceptance criteria
- Users with over 300 edits and 6 months of account age are no longer autopromoted to the temporary-account-viewer group
