This commit also updates the version of `@angular/cli` used for docs examples.
The previous (transient) dependency `@ngtools/webpack` was not compatible with
`@angular/compiler-cli@>=5` and was breaking when running against the local
builds (currently at 5.0.0-beta.2). The version of `@ngtools/webpack` used by
the latest `@angular/cli` version is compatible with `@angular/compiler-cli@5`.
(Coincidentally), this wasn't an issue before fdfeaaf1f, because
pre-verification was run after `test.sh`, during which `aio-builds-setup` was
built.
Now that `deploy-staging.sh` is being run before `test.sh`, we need to build
the `aio-builds-setup` scripts first.
Generate the docs with `yarn docs`.
Test the doc generation code with `yarn docs-test`
The docs are automatically built as part of the `yarn build` task,
so there is no need to rebuild them in the test_aio.sh file
