Opening a zarr behind a S3Config as YAXArray fails

[felixcremer]

When I try to open a zarr that needs credentials and a config as a YAXArray this fails because open_dataset tries to open the zarr with a store string and an empty path.
This is on current main of everything with zarr.jl at 0.11
This failed differently on previous versions but I think that worked at some point.

using Zarr
using YAXArrays
using AWSS3

cfg = AWSS3.AWS.AWSConfig(creds=nothing, region="us-west-2")
z = AWSS3.AWS.with_aws_config(cfg) do # This works
         zopen("s3://mur-sst/zarr-v1")
       end

yax = AWSS3.AWS.with_aws_config(cfg) do # This fails
         open_dataset("s3://mur-sst/zarr-v1")
       end

z = AWSS3.AWS.with_aws_config(cfg) do # This fails and is what open_dataset tries to open the zarr
         zopen("s3://mur-sst/zarr-v1", "")
       end

# This fails because of missing credentials
       zwocfg = zopen("s3://mur-sst/zarr-v1")

@time yaxz = open_dataset(z) # This works but needs 13 seconds with 13 lock conflicts
