Rollup merge of #111844 - GuillaumeGomez:migrate-gui-test-color-4, r=notriddle
Migrate GUI colors test to original CSS color format

I updated the `browser-ui-test` version because I fixed https://github.com/GuillaumeGomez/browser-UI-test/issues/507. If inside a function, the colors were not considered, preventing the second commit of this PR.

Follow-up of https://github.com/rust-lang/rust/pull/111459.
