How to reproduce?

When defining segments as conditions in feature rules, do not allow same segments to be repeated.

For example, this should not be allowed:

// features/myFeature.yml

# ...

environments:
  production:
    - key: "1"
      segments: 
        - foo
        - bar
        - foo # linting should fail here
      percentage: 100

Where to update?

Linter code can be found here: https://github.com/featurevisor/featurevisor/tree/main/packages/core/src/linter

The same might be applicable for conditions as well inside Segments.
