Feature to use local vlm model too

Browse Source 
Hi, This PR is used to let the user use the local repository or the model downloaded in their path. 

I have ran this in my local.
```
from docling.datamodel.pipeline_options import PictureDescriptionVlmOptions

pipeline_options = PdfPipelineOptions()
pipeline_options.do_picture_description = True
pipeline_options.picture_description_options = PictureDescriptionVlmOptions(
     repo_id= "/opt/dlami/nvme/Qwen/Qwen2.5-VL-7B-Instruct",  # <-- add here the Hugging Face repo_id of your favorite VLM
    prompt="Extract the text from the images, if it is table extract the table format.If there are no text give 'No Image Text' response",
)
pipeline_options.images_scale = 2.0
pipeline_options.generate_picture_images = True

converter = DocumentConverter(
    format_options={
        InputFormat.PDF: PdfFormatOption(
            pipeline_options=pipeline_options,
        )
    }
)
```
