[BUG] bundle creates invalid document (refs)

### Describe the bug.

`asyncapi bundle` creates invalid documents.

`main.yaml`
```yml
asyncapi: 3.0.0
info:
title: demo
version: '1'
operations:
A:
$ref: "./_sub.yaml#/components/operations/A"
channels:
A:
$ref: "./_sub.yaml#/components/channels/A"
```

`_sub.yaml`
```yml
components:
operations:
A:
action: send
channel:
$ref: '#/components/channels/A'
messages:
- $ref: '#/components/channels/A/messages/A'
channels:
A:
messages:
A:
$ref: '#/components/messages/A'
messages:
A:
payload:
type: object
```

```sh
asyncapi validate main.yaml
asyncapi bundle ./main.yaml --output final.yml
asyncapi validate final.yml
```

produced invalid output:
```yaml
asyncapi: 3.0.0
info:
title: demo
version: '1'
channels:
A:
messages:
A:
payload:
type: object
operations:
A:
action: send
channel:
$ref: '#/components/channels/A'
messages:
- $ref: '#/components/channels/A/messages/A'
```

### Expected behavior

It should've either updated the refs to root or moved the channels/ops/messages to `components` (if allowed).
