Hangar dependencies point to "null" #1499
Description
Observed/problematic behavior
When publishing a new version to a project that contains a hangar dependency, the href is always null
This happens from both direct upload on hangar and via the hangar-publish plugin
The target URL of the dependency looks like https://hangar.papermc.io/user/project/versions/null
Expected behavior
Clicking the dependency should point to the actual project
Steps to reproduce
Publish a new version with a hangar dependency
Click on the dependency
Points to current-project/versions/null
Other
The project I noticed this problem first: https://hangar.papermc.io/TheNextLvl/Tweaks/versions/3.3.0
The actual dependency url: https://hangar.papermc.io/TheNextLvl/ServiceIO
the problematic url: https://hangar.papermc.io/TheNextLvl/Tweaks/versions/null
URLs work fine
Editing a dependency to set it to a hangar dep doesn't work either, it always acts as URL
