Description

Small update to remove the hardcoded -dev suffix from dev_tags, which is causing tags to be in the format 1.12.0-dev-dev instead of just 1.12.0-dev. I'll clean up the old tags before making the dockerhub repo public, which will be available https://hub.docker.com/r/hashicorppreview/consul.

dev_tags were first introduced in #13084
