* Remove debugging code
* Fix path to github-pr-info.txt, which is used when labeled before
  build completes
* Add a check to skip the build if the build is completed but the PR is
  not labeled with Playground

This commit adds a new workflow `pr-playground.yml` that posts a
Wasm-based PR playground link to the PR when it's labeled with
`playground`.
