Refactor CI and Playground build pipelines

This commit separates "build / test" and "publish" into separate
pipelines to prepare for uploading to GitHub Pages with GitHub Actions:

- A WebApp build CI step is added which compiles the Rust code to Wasm
  and builds the TypeScript code into a bundle. This step never uploads
  to GitHub pages and runs on PRs and merges to trunk.
- A "Publish" workflow is added which builds and uploads to GitHub
  Pages. This workflow only runs on merges to trunk. A concurrency group
  called "pages" is added with canceling of in flight builds if a newer
  commit is pushed to trunk. The publish workflow is no longer published
  on a weekly cronjob.

This commit also contains some cleanups:

- `actions-rs` GitHub Actions are replaced with bare calls to rustup and
  clippy, addressing artichoke/project-infrastructure#265 for the
  playground.
- Caching is removed from `setup-emsdk` action due to an upstream bug:
  mymindstorm/setup-emsdk#20.
- `ruby/setup-ruby` is removed from CI jobs where it is not required.
- The `CARGO_NET_GIT_FETCH_WITH_CLI` env variable is set, porting a
  change from `strftime-ruby`. This should speed up build times when the
  Artichoke git repository is not cached.
