datree image should have a version to prevent side effect

[lrochette]

the image used in the workflows/datree/versions/0.0.1/workflowTemplate.yaml is version-less (therefore latest)

image: datree/codefresh-datree

we should change it to a specific version so no unplanned change are introduced

@danamzulescu-codefresh I checked the docker repo and the only tag is latest.
Can you reach out to datree and have them set a uniq tag for this image please
