Tar cloud YAMLs in cloud build release

Summary:
We want to build a tar of the public cloud YAMLs + a list of the image tags to:
- Make it easier to deploy cloud without requiring kustomize
- Make it easier to deploy cloud in an air-gapped environment

Test Plan: Run the jenkins job, check the generated files: https://storage.googleapis.com/pixie-dev-public/cloud/latest/pixie_cloud.tar.gz
