Rescrape mmdetection segmentation models to suppoer v3 models

[0ssamaak0]

The current version 1.2 is using mmdetection 2.x after upgrading mmcv and removing it as a main dependency (as in #64), we need to reuse the scraping script in models_menu/mmscraper.py to rescrape the models and create new models_json.json

keep in mind that models_json.json has other models like YOLOv8. it's highly recommended to scrape into new json and merge them afterwards.
