chore: Add Usage Trend of InstantSearch Family

[cwtuan]

I’d like to suggest adding a link to the README that shows the usage trend of the InstantSearch family of packages. This link will direct users to a dynamic chart that visualizes the download trends of related packages over the past three years, helping new users evaluate the popularity and adoption of InstantSearch tools.

As a maintainer of npm-compare.com, I’m also happy to implement any other features that could benefit your project, if you find them useful.

Thanks for considering my suggestion!

Thanks for your contribution! This could be interesting, but I wonder what people would learn from the graph? That Vue InstantSearch is not used very much in comparison, or something else I'm missing? Thanks

Thanks for your feedback! I understand your concern. Since Vue InstantSearch currently has fewer users, displaying the trends for all InstantSearch family packages might not provide the most encouraging picture for new users.

To address this, I’ve updated the README to show only the usage trend for instantsearch.js. This package has been growing in popularity, and showcasing this trend will likely give new users more confidence in adopting it.

In the future, if other InstantSearch family packages, including Vue InstantSearch, see increased usage, we can consider adding their trends as well. For now, I recommend starting with the instantsearch.js trend.

Thanks again for considering my suggestion!
