Fix enum value lookup jump

[HolonProduction]

Alternative Followup to #101127 that also sets the correct lookup target and script

Fixes #101089

Known issues:

• With this pr enum values will resolve to a lookup target that points to the actual enum and not only the class containing the enum. The editor is not able to resolve the documentation for this nested target (it is able if the nested element is a class, but it doesn't seem to handle enums). I don't have the insight on how the documentation is resolved to fix this.

My b on merging the prior PR a bit too quickly; feel free to revert those changes here if you deem it necessary

[HolonProduction]

Nah, no need to revert. Just rebased
