Update passbolt docker container

Every passbolt release comes with a container release. Passbolt containers have a image tag that contains the passbolt version so updating them is as easy as changing the image tag.

Of course depending on your container scheduler, or docker-compose you might need to restart the stack or perform some extra steps that are out of the scope of this help site.

As a example if you are running passbolt docker using the docker-compose files provided here you would just need to change the following line:

 image: passbolt/passbolt:<IMAGE_TAG>-debian

Where is the passbolt version that you want to use, for example `2.13.5` and relaunch your composer:

$ docker-compose up -d

Voilà
