mgr/pybind/object_format: fix json-pretty being marked invalid

without this patch you'd get

```
[ceph: root@vm-00 /]# ceph nfs cluster info --format json-pretty

Error EINVAL: Unknown format name: json-pretty
```

this seems to be because valid formats are checked using
the class

```
class Format(str, enum.Enum):
    plain = "plain"
    json = "json"
    json_pretty = "json-pretty"
    yaml = "yaml"
    xml_pretty = "xml-pretty"
    xml = "xml"
```

and then

```
set(str(v) for v in Format.__members__)
```

but that resolves to

```
{'yaml', 'json_pretty', 'plain', 'xml', 'json', 'xml_pretty'}
```

and so json-pretty is marked as invalid. Note that it's also
impossible to pass json_pretty as the format as core ceph
blocks it with

invalid choice: 'json_pretty' (choose from 'json', 'json-pretty', 'xml', 'xml-pretty', 'plain', 'yaml')
