Testing of clustering fails on ubuntu due to CUDA issue.

[meghdadFar]

Right now clustering tests, in particular, tests/clustering/test_clustering.py fails in GitHub Actions, throwing the following error:

lib/python3.10/site-packages/torch/__init__.py:168: in _load_global_deps
    ctypes.CDLL(lib_path, mode=ctypes.RTLD_GLOBAL)
/opt/hostedtoolcache/Python/3.10.11/x64/lib/python3.10/ctypes/__init__.py:374: in __init__
    self._handle = _dlopen(self._name, mode)
E   OSError: libcurand.so.10: cannot open shared object file: No such file or directory

Since the tests run without any problem on Mac OS 11.7.6, this seems to be a CUDA issue on ubuntu-latest (which is the machine on which the Python environment is created and the application is being tested).

cuda is one of the dependencies of torch and torch is a dependency of sentence-transformers.
