Build a push images from Github Actions

[fmasa]

Right now I build and push Docker images via build_and_push.sh script manually. We could not use Docker Hub webhook, because there are dependencies between images and Docker Hub ran image builds out of order (i.e. fmasa/lebeda:7.4-ci which depends on fmasa/lebeda:7.4 was built before this image)

Now we can use Github Actions to build the Docker images in correct order.
