fix(cli): rename repository/service feature flags

- Rename `--enableRepository` to `--repositories`
  (notice the plural form)
- Rename `--enableServices` to `--services`

This commit fixes the inconsistency where `--enableRepository` was
using the singular form, while `--enableServices` was using the plural
form.

It also improves the feature prompt so that the word "enable" is not
repeated twice.
