Fix Ginkgo version in CITATION.cff

[greole]

The version in CITATION.cff is not the most recent, this PR bumps the version to the latest released version 1.8.0.

I always wondered if we should bump the version or not in the citation. My feeling would be not, because the paper doesn't reflect the library content and capacity of version 1.8.0, it maybe does up to 1.3.0 or something like this, in fact.

[greole]

Ah I see your point. I thought the first part is meant for a general citation of the library. And additionally we have the prefered paper section which should state the library version indepently.

[greole]

Looking at the validation guide, especially the title and prefrerred-citation section, I understand it as the current version of the software and the prefrerred-citation is an additional paper which can specify the version separately.

[greole]

There is an example of a mixed authors list with persons and anonymous entries.

authors:
  - given-names: Stephan
    family-names: Druskat
  - name: "The Research Software project"

I guess if we want to distinguish between main named authors and other unnamed authors we could use something like - name: "The Gingko contributors"

or similar.
