UHF-9932

Prevent RTL languages showing up as LTR in ckeditor by overriding the language given to ckeditor.

How to reproduce:

• Setup etusivu-instance
• Make sure your user's ui language is either und or any LTR-language
• Go edit any existing arabic content

Ckeditor should show the arabic as LTR

How to install

• Make sure your instance is up and running on latest dev branch.
  • git pull origin dev
  • make fresh
• Update the Helfi Platform config
  • composer require drupal/helfi_platform_config:dev-UHF-9932
• Run make drush-updb drush-cr

How to test

• Go and edit the arabic content
• See that the content shows up like RTL-language
• See that the editor works as it is expected to work with RLT-language
• See that the page looks OK after saving
