Rollup merge of #111459 - GuillaumeGomez:update-browser-ui-test, r=notriddle

Update browser-ui-test version to 0.16.0

This new version brings one major improvement: it allows to use the original color format in checks (I plan to slowly continue converting colors back to their "original" format, ie the one used in CSS).

It also provides some improvements in some commands API.
