Falcon3-1B-Base has the model.safetensors.index.json file from Falcon3-3B-Base?

[emunsing]

Bug description

When attempting to download Falcon3-1B-Base I get the below error, which is generated because the download package only includes a single model.safetensors file but the model.safetensors.index.json index json expects both model-00001-of-00002.safetensors and model-00002-of-00002.safetensors. This was confirmed by debugging with a breakpoint at the failing line.

This suggests that the wrong model.safetensors.index.json is being downloaded; by comparison with other Falcon models' index files it appears that this is probably an index file from a Falcon3-3B model. Is this issue appropriate in this Github repo, or should it be logged somewhere elsewhere?
