Form not transmitted to ValidatePaneForm

Please post a patch so we can easily review what you are proposing to change. Thanks!

Hi everyone I've solved this one. These changes also fix this issue 🐛 Duplicated error messages Active

Steps to reproduce:
1. Submit your form without checking the agree_terms field.
2. Check your checkbox and try to submit.
3. You will see a validation error that the field is required.

This one makes it possible to submit the checkout after failed validation for Drupal 10.

I am adding a patch file which makes this fix work with translations.

Update the patch for the validation message.
