Switches the integration tests form Puppeteer/webdriver-manager to the
Bazel-managed Chromium/Chromedriver. This is now possible with the new
integration test rule for which we can consult the
`dev-infra/bazel/browsers` toolchain and setup environment variables.
This has been configured already in a previous commit.
This commit also includes some additional small cleanups necessary for
the new integration test rule:
* The `test.sh` scripts have been renamed as they would conflict with
the `test.sh` scripts generated by the integration test rule.
Previously this was not an issue because tests were declared at a
higher-level. As mentioned though this has other downsides and it is
trivial to rename the file.
* Related to the point above, since tests are now declared witin the
actual test folder (for perf e.g.), `package.json` files setting
`"type": "module"` will accidentally cause the `nodejs_test`-generated
files to be considered ESM. This is not correct and likely needs to be
fixed upstream in `rules_nodejs` where explicit `.cjs` extensions
should be used. This is only happening **once** in the `injectable-def`
test so it is acceptable doing that for now.

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
