Update users.json

Hi Nuno Coração!

I hope you're doing well. Could you add my website, [utrodus.com](https://utrodus.com), to the Blowfish Users section?

It's a portfolio and blog developed with Blowfish where I showcase my work in Flutter development and blogging.

Thank you so much for your help!
