Datacite publish argument

This is only partially tested, since the data isn't actually sent off to the test server. If we were to do that in a test, we would accumulate findable and undeletable(?) DOIs.

@yarikoptic I invite followup commits with more comprehensive testing.

Added labels, all green now. I would've preferred avoiding copy pasting data structures across tests and come up with reusable scenarios (otherwise harder to spot relevant code/data) but that I guess could be done later. Let's proceed and release library so could be put to use

FWIW at least in webui indeed "Delete" button in the menu on the left is not available for "Findable" DOIs like https://doi.test.datacite.org/dois/10.80507%2F000003%2F0.210401.2020, but present for "Draft", like https://doi.test.datacite.org/dois/10.80507%2Fdandi.000035%2F0.210729.1456 . Didn't try via API, and indeed we would not want to keep breeding DOIs (even in the test. instance)
