bug: FluentD containerports are only opened for http and forward input plugins

# Problem
ContainerPorts for fluentd are only opened for the http and forward plugins configured in spec.globalInputs.
This makes any other fluentd input plugin unuseable.

### To Reproduce

```
apiVersion: fluentd.fluent.io/v1alpha1
kind: Fluentd
metadata:
name: fluentd
namespace: fluentd
labels:
app.kubernetes.io/name: fluentd
spec:
globalInputs:
- id: in_http
http:
bind: 0.0.0.0
port: 9880
- id: in_syslog
customPlugin:
config: |

@type syslog
@id in_syslog
tag foo
port 5140
bind 0.0.0.0

...
```

Will create a fluentd container with ports `metrics:2021,http:9880`.
The customPlugin port (or any other input plugins) are not being created.

### Expected behavior

Container has open ports for every configured input plugin or the fluentd CRD allows to specify ports like the fluentbit CRD.

### Your Environment

```markdown
- Fluent Operator version: v3.3
```

### How did you install fluent operator?

_No response_

### Additional context

# Code-References
It looks like that the containerPorts are statically coded to be only useable by the forward and http plugin.

# Other issues which are correlated to this
- The inputs.fluentd.fluent.io CRD is also not opening ports.
