UHF-10239

What was done

• Created an image gallery paragraph which can be added to basic page upper and lower content areas as well as landing page.

How to install

• Make sure your instance is up and running on latest dev branch.
  • git pull origin dev
  • make fresh
• Update the HDBT theme
  • composer require drupal/hdbt:dev-UHF-10239
• Update the Helfi Platform config
  • composer require drupal/helfi_platform_config:dev-UHF-10239
• Update the HDBT Admin theme
  • composer require drupal/hdbt_admin:dev-UHF-10239
• Run make drush-updb drush-cr

How to test

• The image gallery should be automatically be added to basic page upper and lower content areas and on landing page to the content area. Make sure it's available in all three. The image gallery will be added to instance related content types in separate pr:s after HDBT and platform config have been merged.
• Add image galleries to a basic page and add different variations to upper and lower content areas.
• Make sure that in the upper area there are two images next to each other and in the lower area there are three
• Try out the different aspect ratios of the image gallery
• Test that the photographer comes from the image media entity below the image.
• Test that the design is responsive and works in each breakpoint
• Try out translating the paragraph, it should work normally
• Test that the validation works, meaning there should be at least two gallery items always. It should give an error if there's only one item in a galley.
• Check that code follows our standards
