these are now removed.
The getModuleScripts() are now deprecated as well, always returning
an empty array. To be removed in 1.34.
Depends on commits for bundled/wmf-deployed extensions that
remove the last few remaining callers to the deprecated functions
in: 3D, Collection, Flow, GlobalUserPage, and Wikibase.
