iOS Cordova release build command seems incomplete

**URL**
https://ionicframework.com/docs/deployment/app-store
(source at `src/pages/deployment/app-store.md`)

The build command for a release build states
`ionic cordova build ios --prod`

while every other platform is documented as:
`ionic cordova build --prod --release`

Is there a reason why `--release` was omitted here? After all, `--prod` is just an alias for underlying configuration selection (`--configuration=production`), but it's the `--release` flag that is used by cordova to mark a release build (and then pass it onto respective cordova-ios, cordova-android, etc.

Open src/pages/deployment/app-store.md and compare the iOS release command with the other platform commands and the issue's explanation of --prod and --release. Confirm whether the documented command should include --release; done means the documentation is corrected if the omission is unintended, or the reason is clarified.
