[Docker image 7.3.0, 7.4.0 and 7.4.1] HEALTHCHECK port is set to 80 and not 8080

The healthcheck added to the Dockerfile : HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 CMD curl -f http://localhost/squash/isSquashAlive || exit 1 is by default set on port 80.

Squash is set by default to listen to 8080, and thus by default doesn't respond to 80, causing the container to appear unhealthy.
