Docker: Build and Push #1483

# This workflow is used to build and push the Docker image for n8nio/n8n and n8nio/runners
#
# - Uses docker-config.mjs for context determination, this determines what needs to be built based on the trigger
# - Uses docker-tags.mjs for tag generation, this generates the tags for the images
