chore: bump version

the goal was to remove "variables" when it's empty, but this resulted in
the original value being used if all of the variables contained store
paths. This is not supposed to happen and thus fixed with this.

-To create a basic pipeline, configure it by setting `ci` in `perSystem`.
+## Usage (with flake-parts)
