[BUG]: github_issue_labels data source inconsistent in docs

### Expected Behavior

The doc for data source github_labels is inconsistent.
I have checked github_issue_labels is working while github_labels is not.

### Actual Behavior

github_labels is not valid data resource,
github_issue_labels is valid data resource.

since github label can be applied to both issue and pr,
github_labels might be more fitting as name.

### Terraform Version

Terraform v1.11.0
on darwin_arm64
+ provider registry.terraform.io/integrations/github v6.5.0

### Affected Resource(s)

- github_issue_labels

### Terraform Configuration Files

```hcl
terraform {
required_providers {
github = {
source = "integrations/github"
version = "~> 6.0"
}
}
}

provider "github" {
token = var.github_token
}

data "github_repository" "repository" {
full_name = var.repository_name
}

data github_issue_labels labels {
repository = data.github_repository.repository.name
}

output github_labels {
value = data.github_issue_labels.labels
}
```

### Steps to Reproduce

after providing proper token and repo name, run
```
terraform plan
```

### Debug Output

```shell

```

### Panic Output
