[UIFe] Yaru needs some updates after UI Freeze

[Carlo Lobrano]

Hello,

hope this is the right way to proceed, and sorry otherwise.
Yaru theme package requires some updates after UI freeze, so I opened a UI
freeze exception ticket to gather all of them

https://bugs.launchpad.net/ubuntu/+source/yaru-theme/+bug/1871586

Could you have a look please?

Thanks,
Carlo
