multiple log format support

Hi,
I have containers that emit logs in containerd format, Which is
```
2022-12-21T16:39:12.398315079Z stdout F 10.1.92.199 - - [21/Dec/2022:16:39:12 +0000] "GET / HTTP/1.1" 200 8430 "-" "kube-probe/1.24+" "-"
```
also, I have a few containers which emit logs in JSON format
```
2023-01-03T10:51:18.181368202Z stderr F {"event":{"severity":"Critical","version":"1.0","eventName":"availability state","eventStatus":"UP"}}
```

Below is my current configuration:
```

@type tail
@id in_tail_container_logs
path /var/log/containers/*.log
exclude_path ["/var/log/containers/fluentd*.log"]
pos_file /var/log/{{.ID}}-fluentd-containers.log.pos
pos_file_compaction_interval 72h
tag kubernetes.*
read_from_head true
follow_inodes true

@type cri
merge_cri_fields true
time_format %Y-%m-%dT%H:%M:%S.%NZ

```

With the above Config, I am only getting logs that are in text format. How can I get logs of both text and JSON formats. Please let me know how I can achieve this goal. Thanks
