Temporarily explicitly declare Spigot dependencies
I don't have the time to deal with whatever the difference between remote and local bash/maven versions is right now.
With 1.17 releasing soon, we'll get to see if this was the issue very shortly.
Worst case scenario the yaml is still messed up, but since the changelog is now the last element, unless it's so badly malformed that the entire action can't run the file should still upload even if the changelog does not.
