Genie v4 and Julia v1.8 compatibility issue: modules_warned_for not defined

Due to an issue caused by the removal of some APIs in Julia 1.8, **Genie v4 apps can not run on Julia 1.8**. This results in a `LoadError: UndefVarError: modules_warned_for not defined` exception when loading a Genie v4 app on Julia 1.8 and above.

Please follow the Genie v4 to Genie v5 migration guide to update your app and make it compatible with Julia 1.8 and above.
