text: Title: Errors with Zarr v3 and da.to_zarr()
  Body: I'm having various issues and errors with `da.to_zarr()` using:
  
  ```
  dask==2025.1.0
  zarr==3.0.1
  fsspec==2024.12.0
  ```
  
  ```
  from skimage import data
  import dask.array as da
  import zarr
  
  dask_data = da.from_array(data.coins(), chunks=(64, 64))
  
  da.to_zarr(dask_data, "test_dask_to_zarr.zarr", compute=True, storage_options={"chunks": (64, 64)})
  
  # Traceback (most recent call last):

  ```
  
  Trying to use a local store has a different error:
  
  ```
  store = zarr.storage.LocalStore("test_dask_to_zarr.zarr", read_only=False)
  da.to_zarr(dask_data, store, compute=True, storage_options={"chunks": (64, 64)})
  
  #   File "/Users/wmoore/Desktop/python-scripts/zarr_scripts/test_dask_to_zarr.py", line 46, in <module>
  #     da.to_zarr(dask_data, store, compute=True, storage_options={"chunks": (64, 64)})
  #   File "/Users/wmoore/opt/anaconda3/envs/zarrv3_py312/lib/python3.12/site-packages/dask/array/core.py", line 3891, in to_zarr
  #     store = zarr.storage.FsspecStore.from_url(
  #             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  #   File "/Users/wmoore/opt/anaconda3/envs/zarrv3_py312/lib/python3.12/site-packages/zarr/storage/_fsspec.py", line 174, in from_url
  #     fs, path = url_to_fs(url, **opts)

  #   File "/Users/wmoore/opt/anaconda3/envs/zarrv3_py312/lib/python3.12/site-packages/fsspec/core.py", line 403, in url_to_fs
  #     chain = _un_chain(url, kwargs)

  #     if "::" in path:
  #        ^^^^^^^^^^^^
  # TypeError: argument of type 'LocalStore' is not iterable
  ```
  
  And also tried with FsspecStore:
  ```
  store = zarr.storage.FsspecStore("test_dask_to_zarr.zarr", read_only=False)
  da.to_zarr(dask_data, store, compute=True, storage_options={"chunks": (64, 64)})
  
  # Traceback (most recent call last):
  #   File "/Users/wmoore/Desktop/python-scripts/zarr_scripts/test_dask_to_zarr.py", line 32, in <module>
  #     store = zarr.storage.FsspecStore("test_dask_to_zarr_v3.zarr", read_only=False)
  #             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  #   File "/Users/wmoore/opt/anaconda3/envs/zarrv3_py312/lib/python3.12/site-packages/zarr/storage/_fsspec.py", line 95, in __init__
  #     if not self.fs.async_impl:
  #            ^^^^^^^^^^^^^^^^^^
  # AttributeError: 'str' object has no attribute 'async_impl'
  ```
  
  Many thanks for your help
