George Kalpakas c997fef08a build(docs-infra): update scripts using Lighthouse to ES modules (#43607)
Update the AIO scripts that use Lighthouse (i.e. `audit-web-app.js` and
`test-aio-a11y.js`) to ES modules. This allows consuming
`lighthouse/lighthouse-cli` [v8.5.0+][1], which also switched to ES
modules.

NOTE:
Switching the `test-aio-a11y.js` script to ES modules is not strictly
necessary, since it invokes `audit-web-app.mjs` via a shell command, but
it was done for consistency.

* Usage:

*
* Runs accessibility audits on several (pre-defined) pages on the specified origin. It fails, if
* the score for any page is below the minimum (see `MIN_SCORES_PER_PAGE` below).
*
* `<origin>` is the origin (scheme + hostname + port) of an angular.io deployment. It can be remote
* (e.g. `https://next.angular.io`) or local (e.g. `http://localhost:4200`).
