- Replace inline wiki data badge code with a render call to a new
shared partial.
- This change promotes code reuse and simplifies the view
templates for cities and weather arts.
- The shared partial handles the condition for displaying the badge
based on the presence of `wiki_data_id`.
This refactor enhances maintainability and adheres to DRY
principles, allowing for easier updates or changes to the wiki
badge display in one location instead of multiple views.
