fix(nx-flutter): restrict ios-language flag to plugin templates only

[lordvins226]

Issue

Starting with Flutter 3.35+, the --ios-language flag is only supported for plugin templates. Passing this flag to other template types (app, module, package) causes the generator to fail with an error.

Failing Command

flutter create --project-name=ui_atom --org=com.example --android-language=kotlin --ios-language=swift --template=module libs/ui/ui-atom

Error: The "ios-language" option is only supported for "--template=plugin".

Fix

This PR restricts the --ios-language flag to only be included when generating plugin templates. For all other templates (app, module, package), the flag is now excluded from the Flutter create command.

The fix also updates the interactive prompts to only ask for iOS language selection when the user is creating a plugin template.

Test Plan

Tested with all template types to verify that only plugin templates include the --ios-language flag in the generated Flutter create command.

Hi @tinesoft . This PR fixes a compatibility issue with Flutter 3.35+ where the --ios-language flag was causing errors for non-plugin templates. Would appreciate a review when you have a chance. Thanks!
