Consider rename of the project

[sdorra]

We should consider a complete rename of the project, because Astro has an API which is also called Content Collections.

I think this is a good idea. I've already seen people be confused by this.

I think this is a good idea, but I found the project only because the name is the same as astro's API lol

Maybe changing the name but keep a info somewhere that the idea is similiar
