Docker push pushes all tags

[fawind]

Before this PR

The previous behavior of docker push was to push all tags of a given image. This changed recently where docker push will just push the latest tag per default (see: moby/moby#40302, docker/cli#2220).

A bunch of users relied on having the ./gradlew dockerPush task as a default task for pushing all tags and are now no longer publishing all tags.

After this PR

The dockerPush task is now an alias for the dockerTagsPush task and will push all available tags per default.

Docker push pushes all tags

Possible downsides?

Maybe we should instead migrate all users that rely on this feature to use dockerTagsPush instead of dockerPush and keep the current behavior?
