Send a request to config.json when downloading model from HF repository

[chmjkb]

Description

Currently, the HuggingFace download count is not incremented when downloading models. HF counts the model downloads by counting the requests sent to the config.json file in the repository root (a HEAD request is enough). This PR sends a HEAD request to the config json, when the model source is our organization.
