Fixed Mixamo left hand finger bone detection for pinky3 and middle 2.

This PR fixes #907.

Here are the fingers detected correctly after the fix.

Describe the bug πŸ’¬

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 πŸ”’

This model has finger bones named correctly (default mixamo rig) but UnityGLTF can't detect them due to the incorrect dictionary mapping. <img width="687" height="651" alt="Image" src="https://github.com/user-attachments/assets/2e50965c-98b4-4d7f-a48c-eb91197c1857" />
