Folder Icons for 'Public' and 'Templates' aren't default in Kubuntu Focal

In Kubuntu 20.04 LTS, there is a visual inconsistency present with the default set of folders in the user's home directory. Note in the screenshot (or in a fresh installation) how most of the folders in the home directory have folder icons with a symbols representing the use for that folder. The 'Public' and 'Templates' folders however, for whatever reason, do not.

== Why does this matter? ==
Given that this release will be an LTS, it will be used by thousands of people for at least 5 years. I believe that fixing small details like this issue will help to increase the overall polish and professionalism of the distribution that will last for those years to come. Other distributions, such as Ubuntu itself, Mint, Fedora, and operating systems like macOS and Windows have symbolic icons on all of their default folders as well, so fixing this paper cut would help bring Kubuntu at parity.

== How trivial is this bug? How easy is this to fix? ==
Admittedly, pretty trivial. I've been resolving this issue in the past by right clicking both folders in Dolphin, selecting 'Properties', clicking the icon, and searching "folder- " in the search box. Then the 'folder-public' and 'folder-templates' icons can be selected.

As such, I assume that this paper cut is also super easy to patch before the final freeze. I don't know what specific package(s) deals with adjusting the icons on the user folders though, so if there are any developers that can provide guidance or make a quick patch I would be very appreciative!
