Some tests for GrowthExperiments fail with updating Codex. We should fix that, so LibUp update Codex to 0.2.2 (and future releases).
Codex was added to the list of repositories in T295420: Add Codex to LibraryUpgrader monitored repos. But @Sgs pointed out to me that based on this search, it does not seem like LibUp is updating repositories with new versions of Codex. (See also T295420#8247738.)
Do we need to do something to enable the updates for e.g. GrowthExperiments?
