Allow multiple instances of the same recognizer through YAML

[Mehrsary]

Change Description

Added support for configuring multiple instances of the same recognizer class (e.g., GLiNERRecognizer) with different parameters through YAML configuration

Example usage:

recognizers:
  - name: GLiNERRecognizer
    type: predefined
    instance_name: "gliner1"
    model_name: "urchade/gliner_multi_pii-v1"
    threshold: 0.4
    ....
    
  - name: GLiNERRecognizer
    type: predefined
    instance_name: "gliner2"
    model_name: "gliner-community/gliner_small-v2.5"
    threshold: 0.25
    ....

Thanks! Would you mind adding a test and example conf for for the test to use? There is a conf folder inside the tests folder.

[Mehrsary]

Yeah, if the overall approach sounds good to you, I'll move it forward and get back to you

@Mehrsary it does look good. We have another PR for input validation so one would need to be merged with the other to make sure the functionality works as expected. I don't mind getting this functionality into the other PR so if you'd like, please add the test cases and we'll merge. Otherwise, we would merge it after the other change.

Please see #1780. It should be handled there but if it isn't, I would suggest to merge 1780 first and add the capability afterwards. Thanks for the work!
