Feat/on navigate entity info relations

[VincentKneip]

This pull request includes the following changes:

• Fixes EntityRelationsWidget querying an old API route /instances (through function OlsApi::getClassInstances()) which has changed in the ols4/v2 API (now named /individuals).
• Added a type object in types.ts containing all the necessary onNavigate functions (to ontology/entity, on disambiguate). This has to be merged with the other advances of onNavigate functions on other dev branches (e.g. #133).
• Added function inferTypeFromTypeArray(types: string[]) : ThingTypeName in util.ts which returns the only ThingTypeName contained in types or throws an error if there are multiple or none (solves the former error of specific property types). Has to be merged correctly with #134.
• Implements a mechanism to correctly display the onNavigate functions in Storybook. Formerly, because of missing support for function parameters in Storybook, only empty functions were displayed, resulting in a confusing behavior. See here: https://github.com/ts4nfdi/terminology-service-suite/issues/137#issuecomment-2379461732.
• Introduces onNavigate functions for EntityInfo- and -RelationsWidget and features a new story for each widget demonstrating its functionality:
