It's not possible to translate a Landing Page.
- add a new Language: Polish (pol-PL) and add it to admin_group in ezplatform.yaml
Steps to reproduce:
1. Login as admin
2. Go to Site -> Site Factory -> "site" Site
3. When previewing the "Home" Landing Page click "Add translation"
4. Select the language "Polish" and base it on English version
5. Click "Create'
The Page Builder opens and allows me to translate the Landing Page
