Fix CUDA trove classifiers & update README install instructions (#695)

Fix CUDA trove classifiers to match [CUDA 11]( https://github.com/pypa/trove-classifiers/blob/521d53011d28fc9490ef83e88eb2464d42dbd633/src/trove_classifiers/__init__.py#L44 ) and [CUDA 12]( https://github.com/pypa/trove-classifiers/blob/521d53011d28fc9490ef83e88eb2464d42dbd633/src/trove_classifiers/__init__.py#L54 )

Also update the README's install instructions for CUDA 11.2+ and CUDA 12

 ```bash
-pip install cucim
+pip install cucim-cu12

-# Install dependencies for `cucim.skimage` (assuming that CUDA 11.0 is used for CuPy)
-pip install scipy scikit-image cupy-cuda110
+Alternatively install for CUDA 11:

+```bash
+pip install cucim-cu11
