[Bug]: `bk artifacts download` the `--path` argument doesn't support `{a,b}` globbing

### Contact Details

github

### What happened?

```
6624 $ bk artifacts download --pipeline platform --path="log/{rspec*.json,minitest.log}"
No artifacts found matching path 'log/{rspec*.json,minitest.log}'.
```

### Version

bk version 3.55.0

### What environment are you seeing the problem on?

_No response_

### Relevant log output

```shell

```

Start with the `bk artifacts download` command and its `--path` argument handling, then reproduce the example against artifacts containing matching files. Trace how path patterns are parsed and verify that brace patterns such as `{rspec*.json,minitest.log}` match and download the expected artifacts.
