✨ feat: Add relay docker image (#1)

## Description

**What(what issue does this code solve/what feature does it add):**

We are adding the `Dockerfile` to build a moq-relay

**How(how does it solve it):**

1. Added `relay.Dockerfile` with all the docker code to build
kixelated's moq-relay.
2. Added `relay.yml` in workflows for building and publishing the docker
image
