here's how you can make the physbones (really quick 4min tutorial) : https://www.youtube.com/watch?v=FzK51_nNXAc
(btw sorry at the beginning in the avatar I was searching where was the dynamic bones to show you xD but didn't check the Armature at first before converting)
If you don't have the dynamic bone package : https://anonfiles.com/6ecb8cj1zf/Dynamic_Bone_1_2_2_unitypackage
The shader is included in the avatar but here's the latest version I've imported : https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project
