fix: ensure DocC uses Swift package plugin in CI

- Remove CI environment check that was skipping DocC generation
- Use swift package generate-documentation which properly uses the DocC plugin
- Package.swift already includes swift-docc-plugin dependency (1.4.0+)
- This should resolve permissions issues by using plugin instead of system DocC
