Add Ontology annotation to package tags

[kMutagene]

This would enable automatic matching of swate template endpoint repository targets, meaning we could auto-validate templates

@Freymaurer first step in this direction is done. Tags are now ontology annotations, see api docs at https://avpr.nfdi4plants.org/swagger/index.html

@Freymaurer since templates and validation will stay separate in mid-term, let's make sure that at least the same tags are used for the packages. What tags should we use in this repo to stay in sync (e.g. from which ontology)?

Hey! The users can use any ontology they like for their templates. Maybe we can reuse some of the logic i added as CI here: https://github.com/nfdi4plants/Swate-templates/blob/main/CI/coherentTagsEnsure.fsx and add the terms from validationpackages
