Declare explicit dependency in hangar publishing block

[NotMyFault]

Currently, releases aren't distributed on Hangar, because of

* What went wrong:
Some problems were found with the configuration of task ':publishPluginPublicationToHangar' (type 'HangarPublishTask').
  - Gradle detected a problem with the following location: '/home/runner/work/fastasyncvoxelsniper/fastasyncvoxelsniper/build/libs/fastasyncvoxelsniper-2.9.1.jar'.
    
    Reason: Task ':publishPluginPublicationToHangar' uses this output of task ':shadowJar' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.
    
    Possible solutions:
      1. Declare task ':shadowJar' as an input of ':publishPluginPublicationToHangar'.
      2. Declare an explicit dependency on ':shadowJar' from ':publishPluginPublicationToHangar' using Task#dependsOn.
      3. Declare an explicit dependency on ':shadowJar' from ':publishPluginPublicationToHangar' using Task#mustRunAfter.

This needs to be addressed in order to restore distribution on Hangar. The logic relies in https://github.com/IntellectualSites/fastasyncvoxelsniper/blob/main/.github/workflows/upload-release-assets-.yml
