Add generateog to build and deploy workflows

- build-generator.yml: add parallel job to build fat JAR + AOT cache
  for generateog.java (renamed workflow to 'Build Generator JARs')
- deploy.yml: restore generateog cache and run OG card generation
  before uploading the site artifact
- .gitignore: add generateog.jar and generateog.aot
