We now commit protocol.ts files during the roll.
New utils/roll_browser.js helps with that.
This makes our installation very shallow:
- build installer;
- download browsers.
This reverts 2 commits:
- "fix(installer): create tmp directory inside `browserPath` (#2498)"
commit 946b4efa3b.
- "feat: support atomic installation of browsers (#2489)"
commit 3de0c087bc.
This addresses installation issues we see in some CI environments.
