Fix the minimal module type.

The code that generates the `minimal` module type is supposed, at some
point, to select classes, individuals, and annotation properties.

However, the rule is incorrectly written as

  --select "classes individual annotation-properties"

which is incorrect because the keyword that ROBOT expects to select
individuals is `individuals` (with a final `-s`) -- `individual` without
a `-s` is ignored.
