Yaru: Gtk3: suggested- and destruction-action buttons need special cased :focus styling

We can take inspiration from bootstrap: https://getbootstrap.com/docs/4.4/components/buttons/

I think it looks really good
I don't know if it's doable though, I'll check

[Feichtmeier]

Nope, doesn't work with gtk :/

I would love this look if we could finally go full 2020 and have flat buttons but :man_shrugging:

This is from the PR

LOL, I had a patch ready for this, but forgot to push it... It looks good, we can use this :D
