[D8] Nested Entity Reference Formatter

I added the Git instructions for non-maintainer users and the PAreview checklist link. Reviewers will check the project and post comments to list what should be changed.

If you haven't done it, yet, please check the PAreview report and fix what needs to be fixed. There could be some false positives; verify that what reported is correct, before making any change.

Hello.
During my module review, I've not found any critical issues.

<strong>Drupal check report:</strong>

$ vendor/bin/drupal-check web/modules/contrib/nested_entity_reference_formatter/
 3/3 [▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓] 100%


 [OK] No errors

Unit tests were passed.

The code well commented and maintainable.

No errors were added to the dblog during my testing of the module functionality.

So, I think the module can be marked as passed the Security Advisory coverage.
