It's a perfect example! Thanks! I'll do the same for rofi-pass!

I'm stuck with my UI tests! :-(

I was relying on `chromedriver` (packaged with ungoogled-chromium), but now
that it's been deprecated… I'm stuck! ^_^'

`geckodriver` is not packaged with icecat. This is why I wanted to a)
download it or b) package it.

The problem is that a) the version I download does not work (a problem
specific to Guix System, I guess, that would be solved by packaging…
another wild guess) and b) it's a bit of work to package.

But, all of sudden, I wonder if `geckodriver` could not be part of
icecat, like `chromedriver` was part of ungoogled-chromium?!

Thanks again for the snippet!
