George Kalpakas ab8199f7c9 build: several minor fixes related to using `puppeteer` (#35381)
This is a follow-up to #35049 with a few minor fixes related to using
the browser provided by `puppeteer` to run tests. Included fixes:

- Make the `webdriver-manager-update.js` really portable. (Previously,
  it needed to be run from the directory that contained the
  `node_modules/` directory. Now, it can be executed from a subdirectory
  and will correctly resolve dependencies.)

- Use the `puppeteer`-based setup in AIO unit and e2e tests to ensure
  that the downloaded ChromeDriver version matches the browser version
  used in tests.

- Use the `puppeteer`-based setup in the `aio_monitoring_stable` CI job
  (as happens with `aio_monitoring_next`).

- Use the [recommended way][1] of getting the browser port when using
  `puppeteer` with `lighthouse` and avoid hard-coding the remote
  debugging port (to be able to handle multiple instances running
  concurrently).

Greg Magolan acfd0edd38 test: use puppeteer in integration tests and to download correct chromedriver (#35049)
This means integration tests no longer need to depend on a $CI_CHROMEDRIVER_VERSION_ARG environment variable to specify which chromedriver version to download to match the locally installed chrome. This was bad DX and not having it specified was not reliable as webdriver-manager would not always download the chromedriver version to work with the locally installed chrome.

webdriver-manager update --gecko=false --standalone=false $CI_CHROMEDRIVER_VERSION_ARG is now replaced with node webdriver-manager-update.js in the root package.json, which checks which version of chrome puppeteer has come bundled with & downloads informs webdriver-manager to download the corresponding chrome driver version.

Integration tests now use "webdriver-manager": "file:../../node_modules/webdriver-manager" so they don't have to waste time calling webdriver-manager update in postinstall

"// resolutions": "Ensure a single version of webdriver-manager which comes from root node_modules that has already run webdriver-manager update",
"resolutions": {
"**/webdriver-manager": "file:../../node_modules/webdriver-manager"
}
This should speed up each integration postinstall by a few seconds.

Further, integration test package.json files link puppeteer via file:../../node_modules/puppeteer which is the ideal situation as the puppeteer post-install won't download chrome if it is already downloaded. In CI, since node_modules is cached it should not need to download Chrome either unless the node_modules cache is busted.

NB: each version of puppeteer comes bundles with a specific version of chrome. Root package.json & yarn.lock currently pull down puppeteer 2.1.0 which comes with chrome 80. See https://github.com/puppeteer/puppeteer#q-which-chromium-version-does-puppeteer-use for more info.

Only two references to CI_CHROMEDRIVER_VERSION_ARG left in integration tests at integration/bazel-schematics/test.sh which I'm not entirely sure how to get rid of it

Use a lightweight puppeteer=>chrome version mapping instead of launching chrome and calling browser.version()

Launching puppeteer headless chrome and calling browser.version() was a heavy-handed approach to determine the Chrome version. A small and easy to update mappings file is a better solution and it means that the `yarn install` step does not require chrome shared libs available on the system for its postinstall step
