Describe the bug 💬

Two mixamo finger bone keys are wrong on the left hand. Avatar creation can't detect those 2 bones.

This can be seen in the bone assignment preview in Animation tab (this is a feature I submitted as a PR but not merged yet).

Steps to reproduce 🔢

This model has finger bones named correctly (default mixamo rig) but UnityGLTF can't detect them due to the incorrect dictionary mapping.
