Add build-image.yml deployment workflow for the docker image

This is almost the same deployment workflow we use in data-pipelines
repository to build, tag and push the image to ECR:
https://github.com/iFixit/data-pipelines/blob/main/.github/workflows/build-image.yml

Saved the `role-to-assume` value in repository variables in the repo.
