Deletes an email design theme.
You can't retrieve or restore a deleted email design theme.
Emails that were already composed with the email design theme aren't affected, because the Wix email
editor copies the theme's body into the email at compose time rather than referencing it.
You can only call this method when authenticated as a Wix app or Wix user identity.
This method doesn't return any custom errors, but may return standard errors. Learn more about standard Wix errors.
