ci: Fix Chrome tests on Windows in GitHub Actions (shaka-project#5548)

GitHub started installing "Chrome for Testing" builds on Windows and
Mac. Unfortunately, these builds don't have support for H264 and AAC
codecs, which we need in our tests.

This fixes the issue by explicitly installing an official build of
Chrome on Windows, to overwrite the "Chrome for Testing" build.
