[RFC] Fix reviewstack.dev deploy by removing broken Docker container dependency take 2

[ajaymenon]

Summary

The repo used to have a CI workflow that built an Ubuntu 22.04 Docker image (generated by ci/gen_workflows.py as sapling-cli-ubuntu-22.04-image.yml) and pushed it to GitHub Container Registry as ghcr.io/facebook/sapling/build_ubuntu_22_04:latest. At some point, that workflow and its Dockerfile were removed from the repo, but two workflows that depend on that image were never updated:

• reviewstack.dev-deploy.yml
• sapling-addons.yml

So every time either of those workflows runs, it tries to pull an image that no longer exists, and fails immediately at container initialization.

Example failure on main: https://github.com/facebook/sapling/actions/runs/21693937235/job/62559938248

Test Plan

Not 100% sure how to test this tbh. I tried to add a trigger to get GHA to pick up the change and see if the deploy action would succeed but it looks like I don't have permissions to do that.

ubuntu-22.04 should already have node and yarn so the build deployment should work without any custom dependencies.

Redo of #1208
