Add PeerReview as a publication type

Is your feature request related to a problem? Please describe.

PREreview uploads peer reviews to Zenodo with a 'Journal Article' type (e.g. https://zenodo.org/record/6207581). This isn't correct, but there isn't a type suitable for peer reviews.

Describe the solution you'd like

'Peer Review' added as a publication type.

Describe alternatives you've considered

Using 'Other' as a type.

Additional context

#2206 refers to changes based on the DataCite 4.4 schema, which added PeerReview as a resourceTypeGeneral property.

I second this request. Using the DataCite API I cannot identify Peer review items if they are not given the appropriate resource type

Just spotted that #2390 added support.
