release.sh: rely on git and docker only

[sylvaingaudan]

The release scripts relies on a couple of libraries for building the release. It is safer to be more platform independent, therefore, we can rely on docker, curl and git only. For the time being, sed is also accepted. Therefore, the following libraries should be "dockerized" in the script:

• npm @ l4, l184-l187, l193, l196
• mvn @ l20, l122, l123, l265
