fixes https://github.com/matomo-org/matomo-icons/pull/22 (icons now keep their transparency making them look nicer with non-white backgrounds (dark theme))
fixes https://github.com/matomo-org/matomo-icons/issues/23 (add wearable icon)
@Findus23 looks good but seems a lot of screenshots will need updating
Updated all UI tests where the icon changes were the only thing that changed.
Thanks @Findus23
