Provide way to translate Button language (Submit) into other languages, using Drupal core string translation or other methods

Problem/Motivation

Our team has recently created a Spanish (espanol) version of our English survey. This worked generally very well, but we noticed that there does not appear to be a way to translate some of the button labels, for example "Submit".

Proposed resolution

Please provide a way to translate these button labels. Perhaps the labels could be mananged using the core Drupal "t" function, so that side admins can create a string translation through the "User interface translation" admin page: /admin/config/regional/translate

OR, provide some other method to override the button labels in the survey configuration.
