Verification

Tested with es-MX-tutorial.json:

1. The file contained an untranslated $? in the Line array.
2. I tested whether the Google Translate API could successfully translate $? by running the updated verify-locales.ts script.
3. After running the script, I verified that the new es-MX-tutorial.json was generated correctly, with the $? replaced by the translated content.

Note:

1. I noticed that the contributor who added $? had made a mistake: there should have been five $? entries in the Line array, representing five lines of dialogue, instead of just one. So, I corrected the file by replacing the single $? with five $?, then re-ran the verify-locales.ts script. The script processed the corrected Line array and generated the expected output, confirming the functionality works as intended.

2. I discovered that the language and region fields in zh-TW-tutorial.json were incorrect while trying to resolve this issue.
