bug: missing make manifests and make docs-update before commit

[antrema]

Describe the issue

I found some discrepancies between code and CRDs description/Documentation:
code [apis/fluentd/v1alpha1/plugins/common/buffer_types.go]:

// The number of threads to flush/write chunks in parallel  
// +kubebuilder:validation:Pattern:="^\\d+$"  
FlushThreadCount *string `json:"flushThreadCount,omitempty"  

Whereas in CRDs
crds [charts/fluent-operator/crds/fluentd.fluent.io_clusteroutputs.yaml]:

flushThreadCount:
description: The sleep interval (seconds) for threads to
wait for the next flush try(when no chunks are waiting)
pattern: ^\d+$
type: string

To Reproduce

launch the commands:
make manifests
make docs-update

Expected behavior

No modification after launching these commands

Your Environment

- Fluent Operator version: #N/A
- Container Runtime: #N/A
- Operating system: #N/A
- Kernel version: #N/A

How did you install fluent operator?

#N/A

Additional context

#N/A

// The number of threads to flush/write chunks in parallel
// +kubebuilder:validation:Pattern:="^\d+$"
FlushThreadCount *string `json:"flushThreadCount,omitempty"

The following two files should be consistent with the code, the other docs like charts and manifests are all generated based on the following two files.
https://github.com/fluent/fluent-operator/blob/master/config/crd/bases/fluentd.fluent.io_clusteroutputs.yaml#L113
https://github.com/fluent/fluent-operator/blob/master/config/crd/bases/fluentd.fluent.io_outputs.yaml#L112

The cards in config/crd/bases should be automatically generated by running make generate which is included in make test, so users should run make test everytime they change the crd definition code. Users shouldn't change files in config/crd/bases manuallyright? @wanjunlei

@benjaminhuo I didn't make the changes manually, I launched make manifests and make docs-update to generate the files from the code. All my changes have been obtained by above commands, not manually
EDIT: I think there was just an oversight in a previous commit/PR
