Address review feedback on #49 requesting consistent log levels across from_huggingface methods.

Changes

• Changed logger.info to logger.warning for checkpoint_path logging in _load_pipeline_with_retries (line 1219)
• Restores consistency with Civitai loaders at lines 1746, 1988, 2230 which all use logger.warning

# Before
logger.info(
    f"checkpoint_path: {hf_checkpoint_status.model_status.download_url}"
)

# After  
logger.warning(
    f"checkpoint_path: {hf_checkpoint_status.model_status.download_url}"
)
