Infinite adding EOL

Hi!

I have a YAML file embedding a Jinja template (cames from Ansible):

```yaml
list: >-
[
{% for host in servers %}
{"ip": "{{ host }}"},
{% endfor %}
]
```

Using the dry flag, everything seems ok:

```bash
$ yamlfmt -dry test.yaml
2024/04/23 13:49:10 No files will be changed.
```

Without the dry flag a new line is added:

```bash
$ yamlfmt test.yaml
$ cat test.yaml
list: >-
[

{% for host in servers %}
{"ip": "{{ host }}"},
{% endfor %}
]
```

Every time I run `yamlfmt` a new line is added.
