feat: Proper Emoji support in Chrome images

We often have flaky tests around emoji rendering. Maybe we can improve
the test quality by adding a proper emoji font.

The existing install-noto-image script wasn't utilized and could be
simplified anyhow. Furthermore I think it is fine to install the font
when Chrome is installed, given that we use the Chrome images for
integration tests with the browser.
