ci: add deployment workflow for GitHub Actions

This commit introduces a new GitHub Actions workflow, deploy.yml, for automating deployment to Workers whenever a release is pre-released or released. The workflow includes steps for fetching sources, caching cargo dependencies, installing the stable toolchain and worker-build, building with worker-build, and deploying to Workers. The concurrency setting ensures only one workflow runs at any given time per branch to prevent conflicts.
