Cloudpathlib does not automatically resolve paths that contain `..`

When `..` are in the path, the AzureBlobPath fails to list directory with

```
azure.core.exceptions.ResourceNotFoundError: The specified path does not exist.
```

Interestingly, the metadata to identify whether a path exists, is dir, etc., works just fine.

In my opinion, this should work since `pathlib.Path` works this way.

```python
from pathlib import Path
# Create directroy
Path("root/test/test2").mkdir(parents=True, exist_ok=True)
p = Path("root/test/test2")
assert (p.exists(), p.is_dir()) == (True, True)
assert list(p.iterdir()) == []
p = Path("root/test/../test/test2")
assert (p.exists(), p.is_dir()) == (True, True)
assert list(p.iterdir()) == []
```
