Describe the bug

Instead of being properly included inside the git lfs, these models are coming down as part of the git clone itself.

Reproduction instructions

System Information

This happens on a RHEL 8.4 LoZ server and a Ubuntu 20.04 WSL2 instance. The git clone shown above should be sufficient to recreate the handling.

Notes

No additional notes needed at this time. My plan is to come back through and clean this up myself. It should be a simple adjustment.

[messerb5467]

476, #460, and #442 might be of interest to some people and I'd also like to understand any testing that should be run before simply making those updates.

[messerb5467]

I can come through and clean this up as time allows though.
