Update order of images in docker image tag command

[nebojsatomic]

There was a mistake in the command for tagging an image that you have present in your list of images, order should be like this: docker image tag ALREADY_PRESENT_IMAGE IMAGE_THAT_YOU_WANT_TO_PUSH not the other way around

Not sure if there's a direct mistake on the page though; the example looks to continue from the example shown a couple of lines above that shows that an image was built and tagged as my-username/my-image;

docker build -t my-username/my-image .

Hm, yes,
but it is a bit confusing if you already have a built image with another name ( not my-username/my-image ) and you want to push my-username/my-image.
The text above docker image tag says "If you've already built an image" which could mean that you might not have to do the docker build -t, and you could have named your image previously web:latest for example.

Anyway, whatever you decide, is fine with me :)
