Assert Section Signals Invalid JSON For Array With String Values
### I have checked the following:

- [x] I have searched existing issues and found nothing related to my issue.

### This bug is:

- [ ] making Bruno unusable for me
- [ ] slowing me down but I'm able to continue working
- [x] annoying
- [x] this feature was working in a previous version but is broken in the current release.

### Bruno version

3.1.4

### Operating System

macOS Tahoe 26.3.1 (a)

### Describe the bug

I usually have some basic assertions for all requests. I noticed that Bruno is failing a simple `res.body` `isJson` assertion now for some responses that are just a collection of string values; for instance:

```javascript
[
  "A55001213ZX0A"
]
```

### .bru file to reproduce the bug

```bru
meta {
  name: Some Identifier
  type: http
}

get {
  url: {{api-host}}/resource/{{resource-id}}
  body: none
}

headers {
  Accept: application/json
}

vars:pre-request {
  resource-id: A55001213ZX0A
}

assert {
  res.status: eq 200
  res.body: isJson
}
```
