sample datasets cannot be created in Dataverse 5.10+ due to backward incompatibility with regard to licenses

Multiple licenses were introduced in 5.10 with this PR:

• https://github.com/IQSS/dataverse/pull/7920

Since then, the datasets in this sample data repo can't be created. You'll get Error parsing dataset json

As far as I know, at minimum, you have to make this change:

-    "license": "CC0",
+    "license": "CC0 1.0",
