replace helm for ivy

After experiencing these three packages, I liked helm, but to be honest,
I wasn't using all of its features and I was looking for a lighter and faster solution.
That's why, it's already a few years since I chose ivy and which corresponds entirely to my workflow.
Please note that my choice may vary according to your criteria 😊
