build-prod-release.yml

# Create a Docker build for a production release
# To trigger a release:
#    Update the version numbers in portal-core and portal API pom files
#    Tag with v<POM_VERSION> e.g. v6.3.0
#    This action will compare the pom version with the tag v# to ensure they match
#    If they do it will build the new image and push it to the GitHub Container Registry tagged with that version
#    Check the new image appears in the container registry and that the tags are correct
# To Deploy:
#    Goto Azure and make a new revision of portalapi-prod
#    Select the new version number as the image tag name
