bug: operator pod restarting due to controller-runtime.source errors

### Describe the issue

I'm running into an issue building a fluent-operator image using the Makefile, or using the `go build ...` invocation and packaging the resulting `manager` binary into an image. Either approach results in pod restarts when deploying the operator.

The errors look like the following:

```
kubectl logs -n fluent fluent-operator-55dd7bc945-kthgm
```

### Example MultilineParser error using `docker build` image

### Example ClusterMultilineParser from `go build...` image

```

Both methods will show both Cluster/Multiline errors and the pod will restart. The operator will however create fluent-bit and fluentd pods given the appropriate manifest.

### To Reproduce

## build the image
```
cat VERSION
v2.8.0

docker build --platform linux/arm64 -f cmd/fluent-manager/Dockerfile . -t k3d-k3d.localhost:5005/fluent-operator:v2.8.0

docker push k3d-k3d.localhost:5005/fluent-operator:v2.8.0
```

## helm install
```
helm repo add fluent https://fluent.github.io/helm-charts
helm install fluent-operator --create-namespace -n fluent fluent/fluent-operator --set operator.container.repository=k3d-k3d.localhost:5005/fluent-operator --set operator.container.tag=v2.8.0
```

### Expected behavior

The pod should not be restarting and throwing errors about CRDs.

### Your Environment

- Fluent Operator version: `v2.8.0`
- Container Runtime: `containerd://1.7.15-k3s1`
- Operating system:
```
ID=wolfi
NAME="Wolfi"
PRETTY_NAME="Wolfi"
VERSION_ID="20230201"
HOME_URL="https://wolfi.dev"
```
- Kernel version: `Linux d186e0ca7a21 6.6.16-linuxkit #1 SMP Fri Feb 16 11:54:02 UTC 2024 aarch64 Linux`

### How did you install fluent operator?

Using helm:

```
helm repo add fluent https://fluent.github.io/helm-charts
helm install fluent-operator --create-namespace -n fluent fluent/fluent-operator --set operator.container.repository=k3d-k3d.localhost:5005/fluent-operator --set operator.container.tag=v2.8.0
```

### Additional context

Running with the `kubesphere/fluent-operator:v2.8.0` image explicitly, or by not setting the `operator.container.repository` value in the helm chart results in no errors.
