fix: Earthly integration tests use 'earthly/dind' container | NPG-000 (#537)

# Description

CI tests are breaking because Earthly tries to install docker in
containers that don't have it, causing unexpected timeouts. As
recommended by Earthly Docs,
https://docs.earthly.dev/best-practices#use-earthly-dind , this PR
updates integration tests to address this problem.
