Enable accessing resources in DataONE with de-referenceable HTTP IRIs

DataONE does a lot with Linked Open Data (LOD) but we could do more. Last year, we established a PIRI Service that gives us a way to reference and resolve DataONE resources in LOD contexts but this falls short of a complete LOD experience because we don't expose these IRIs in any user interfaces.

Now that we have a PIRI space, we should try to find the ways in which we can refactor existing user interfaces to use IRIs of this form to make it easier for users to reference resources (packages, people, etc). This might just look like putting anchor tags in the right places in our web views with the right URLs so users can copy the right thing.

Related to this is how we're doing citation strings like those on the top of our dataset landing pages. When datasets have a DOI, we set the URL string to doi:10..... But when the dataset has a UUID identifier, we are just putting the text urn:uuid:xyz which isn't super useful. With the PIRI space, we can use https://dataone.org/datasets/urn:uuid:xyz.
