non-serverless-deploy.yml

# This action is to orchestrate the non-serverless stuffs deployment
# to make sure playwright e2e test is run post-deployments.
# The reason we need to do this hack is because there's currently no way
# to use "workflow_run" trigger with requirement being all depdency workflows'
# complete. More here: https://github.com/community/community/discussions/16059
# Side note: we need to follow .github/workflows convention https://docs.github.com/en/actions/using-workflows/reusing-workflows
