fix: fsspec download a single file instead of downloading files that match pattern (#541)

### Fixes:
- Use `get_file` instead of `get` method to download file in `fsspec`
based connectors.


`get` matches file name patterns and doesn't allow to fetch files that
use some special characters (e.g. `[` or `]`)
