Added a Bear blog like button

Thanks to Naty, and her post, I discovered iine. It enables you to show appreciation for a post, as you can see on Bear blogs. A couple of months ago, I tried to find something similar for Hugo, but, I gave up ot the end. But, thanks to Naty’s research, and Oscar’s work, he’s the developer behind iine, you can send now a simple like to each post. 🙏
