Add `opencv-contrib-python` and `opencv-contrib-python-headless`

### Solution to issue cannot be found in the documentation.

- [x] I checked the documentation.

### Issue

Currently, this recipe does not match the metadata of the `opencv-contrib-python` or `opencv-contrib-python-headless`. So it would be great to add them to the added metadata, as mentioned in https://github.com/conda-forge/staged-recipes/issues/29115#issuecomment-2677143402.

It is an official OpenCV package, from [the documentation](https://pypi.org/project/opencv-contrib-python/), it seems the `-contrib` versions ship extra/contrib packages. You can see the extra modules [here](https://docs.opencv.org/4.x/).
