Use named arguments in DaskFinder.find_spec

Use named arguments in DaskFinder.find_spec

Follow the base class argument names as in MetaPathFinder.find_spec per
https://docs.python.org/3.13/library/importlib.html#importlib.abc.MetaPathFinder.find_spec

This allows find_spec callers to use keyword arguments for path and target.

This fixes the following import error for Cirq due to mismatched arguments of DaskFinder.find_spec

# in fresh venv for Python 3.12
$ pip install cirq-core rapids-dask-dependency
$ python -c "import cirq"
...
  File "/tmp/t312/lib/python3.12/site-packages/cirq/_import.py", line 66, in find_spec
    spec = self.finder.find_spec(fullname, path=path, target=target)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: DaskFinder.find_spec() got an unexpected keyword argument 'path'

$ pip uninstall rapids-dask-dependency
$ python -c "import cirq"
# works as expected

Thanks for this fix @pavoljuhas! Do you know what version of RAPIDS is installed on the systems where this issue is being experienced? That changes the branch that we would merge this change into.

Do you know what version of RAPIDS is installed on the systems where this issue is being experienced?

The Colab environment where it shows has rapids_dask_dependency version 24.12.0.
The commit 2304660 which introduced the code is in all branches starting from branch-24.06, so ideally the fix would apply to all branches that are still maintained.

Thank you for quick response!

Changes looks good to me. Also not sure exactly which branch this should go to
