feat(readme): add badge stars instead of static stars

[thenaim]

Hello!
I think it would be cool to use badges instead of static statistics about stars. If you approve, I will add badges to all other repositories.

Please read the Contribution guidelines. The star count is updated with script, so you shouldn't edit README.md directly (take for example this commit)

Hi thx for the idea

two problems may emerge :

1. Graphics are too bold, it's gonna kill the readability
2. Numbers of http calls in your browsers for each image

@orestesgaolin where is the script located and when is it being run?
