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

[pdurbin]

Multiple licenses were introduced in 5.10 with this PR:

• Support for configurable list of licenses dataverse#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",

This will be included as pm.trivial. & pm.phil.

I just made the following PR to fix this:

• deal with license backward incompatibility #33
