make sure we use latest released amw-relayer

[arturrez]

Why this should be merged

right now we use latest awm-relayer docker image that might not be an issue as https://hub.docker.com/r/avaplatform/awm-relayer/tags contains test images

How this works

now it queries latest released version and uses it

How this was tested

by running wiz command and verifying that container tag matches released latest awm-relayer version
before

ubuntu@ip-172-31-18-165:~$ docker ps
CONTAINER ID   IMAGE                              COMMAND                  CREATED              STATUS              PORTS     NAMES

after

ubuntu@ip-172-31-22-49:~$ docker ps
