Bugfix: error messages aren't displayed as translated strings

[handeyeco]

Summary:

Proposing a bug fix for error messages not showing up as translated: https://khanacademy.slack.com/archives/C06FULVQLSV/p1738014199191129?thread_ts=1738012970.693379&cid=C06FULVQLSV

What I thought we were doing: Originally I thought strings were getting replaced during the translation process (I don't know why I thought that). So we were mapping error codes to error strings directly off of strings.

What we were actually doing: strings isn't actually changed, it's used to make a new object that has all of the translated strings in it. So we were pulling the English strings off of the base object that was used to create a separate translated object.

What this PR does: instead of pulling from strings, we instead pass the translated strings into mapErrorToString. Then we map an error code to a key that we use to access the translated message from the passed in object.

Test plan:

• Go into a non-English language (like Portuguese)
• Go to a Radio widget that requires multiple selections
• Select one right answer, but not all right answers
• Submit question
• There should be an error message displayed
  • broken: that message will be English
  • patched: that message will be Portuguese
