Add contributor affiliation data to metadata pushed to Datacite

[peetucket]

Affiliations associated with contributors was added in sul-dlss/happy-heron#3189 and sul-dlss/happy-heron#3198
Mappings specs to cocina for this data were provided in sul-dlss/happy-heron#3099

We need to use the new mappings to add affiliation information associated with contributors to the metadata generated when sending to DataCite.

This should happen as part of the update-doi step in common-accessioning, which makes a call out to DSA to run the UpdateDoiMetadataJob job, which is where the update will likely occur.

Note: we ran into a problem with affiliations in the UI for H2: the 3 levels of nesting using reform were buggy in an unacceptable way for exposing the users to the possibility of adding affiliations. As such, this ticket may be moot.

I started this ticket before ^^ was known.

I have a branch up with code and the beginnings of specs: cocina-to-datacite-affiliations

While writing specs for my code in the cocina-to-datacite-affiliations branch, I ran into some problems needing @arcadiafalcone's help:

1. the specs need to start with the affiliations in cocina, not as xml or whatever. (see lower comments in Map affiliation and multipart organizational contributor fields to Cocina and DataCite happy-heron#3099, which were the specs for this work but are in xml)
2. presumably the specs in h2 for the affiliations cover the cases that we would need to cover. (see https://github.com/sul-dlss/happy-heron/blob/main/spec/services/cocina_generator/description/affiliations_generator_spec.rb, https://github.com/sul-dlss/happy-heron/blob/main/spec/services/cocina_generator/description/contributors_generator_spec.rb#L1111). The specs in Map affiliation and multipart organizational contributor fields to Cocina and DataCite happy-heron#3099 do not cover all these cases.

@ndushay I'm not sure I fully understand the second point above - are you saying that all of the existing specs should have versions with affiliation, or are there specific ones you've identified as missing?

This is on hold as the H2 UI couldn't do affiliations properly with reform.
