gh gist create only shows privacy status when filename is provided #7644

Describe the bug

When creating a gist with gh gist create, if you do not specify a filename the output of the command does not indicate if it is a public or secret gist.

$ gh --version
gh version 2.31.0 (2023-06-20)
https://github.com/cli/cli/releases/tag/v2.31.0
$ echo foo | gh gist create
- Creating gist...
✓ Created gist
https://gist.github.com/seanbright/...
$ echo foo | gh gist create --public
- Creating gist...
✓ Created gist
https://gist.github.com/seanbright/...
$ echo foo | gh gist create --filename foo.txt
- Creating gist foo.txt
✓ Created secret gist foo.txt
https://gist.github.com/seanbright/...
$ echo foo | gh gist create --filename foo.txt --public
- Creating gist foo.txt
✓ Created public gist foo.txt
https://gist.github.com/seanbright/...

Note that only the last 2 where --filename was provided are showing secret and public in the output.

Steps to reproduce the behavior

1. Type $ echo foo | gh gist create --public and note that the output does not show public
2. Type $ echo foo | gh gist create --public --filename foo.txt and note that the output does show public

Expected vs actual behavior

I expect the privacy status to appear in the output unconditionally.
