Content injection between Hits for Vue InstantSearch

We recently published a guide on [how to inject custom content between hits](https://www.algolia.com/doc/guides/building-search-ui/ui-and-ux-patterns/injecting-content/react/), for React InstantSearch, and we'd like to gather interest in adapting this guide for Vue InstantSearch.

## What's Content injection between Hits?

Content injection consists of inserting data between search results. This pattern can be helpful for a variety of use cases:

- **Displaying promotional or editorial content** based on the search parameters, like the query or active refinements
- **Inserting promoted brand banners** between hits
- **Showing customized suggestions** based on the user profile
