refactor(events): update event organizer details to use host data from api

[Robert27]

This pull request includes several changes to the rogue-thi-app project, focusing on updating event host information and removing redundant data. The most important changes include updating the event host details in various components and removing the clubs.json data file.

Updates to event host details:

• rogue-thi-app/components/cards/EventsCard.jsx: Modified the event card to display the host's name and other details conditionally.
• rogue-thi-app/lib/backend/neuland-api.js: Updated the GraphQL query to fetch host details (name, website, and Instagram) instead of the organizer.
• rogue-thi-app/pages/events.jsx: Removed references to clubs.json and updated the code to use the host details directly from the event data. [1] [2] [3] [4]

Removal of redundant data:

• rogue-thi-app/data/clubs.json: Deleted the clubs.json file as it is no longer needed.
