fix(deps): don't auto-install detox & react-native (#5620) (#5621)

@codeceptjs/detox-helper was listed under optionalDependencies, which
npm/pnpm install by default. It hard-depends on detox and react-native,
so every codeceptjs install pulled in those heavy packages (and the
dtrace-provider build script) even though core never requires the Detox
helper — it is a user-configured external helper.

Move it to devDependencies (still needed for in-repo helper docs
generation). Users who need the Detox helper install it separately.
