Subject: [PATCH 11/13] fix: imrpove CI stability and add comments

* Improve CI stability by only grabbing patch updates. This may when npm
  install runs we will not download a version of Playwright which will
  be incompatible with the browser binaries installed by CI.
* Add CI code comments about the Playwright issue that we ran into.
