fix: don't treat double quote enclosed text as JSON (#2544)
### Summary

Closes #2444. Treats JSON serializable content that results in a string
as plain text. Even though this is valid JSON per [RFC
4627](https://www.ietf.org/rfc/rfc4627.txt), this is valid JSON, but in
almost every cases were really want to treat this as a text file.

### Testing

1. Put `"This is not a JSON"` is a text file `notajson.txt`
2. Run the following

```python
from unstructured.file_utils.filetype import _is_text_file_a_json

_is_text_file_a_json(filename="notajson.txt") # Should be False
```
