### Terraform CLI and terraform-plugin-docs Versions

```

```

### Provider Code

```go
func resourceWireguardAsymmetricKeyImport(d *schema.ResourceData, m interface{}) ([]*schema.ResourceData, error) {
// d.Id() is the argument passed to terraform import
private_key := d.Id()
key, err := wgtypes.ParseKey(private_key)
if err != nil {
return nil, err
}
d.Set("private_key", key.String())
d.Set("public_key", key.PublicKey().String())
d.SetId(key.PublicKey().String())
return []*schema.ResourceData{d}, nil

### Expected Behavior

One introduction for how to import, e.g. previously in v0.21.0:

> ## Import
>
> Import is supported using the following syntax:
>
> ```shell
> terraform import wireguard_asymmetric_key.example "EFr5/97eoK32SeMingmUqJpE4TL21nckcl2jQ9ZT82g="
> ```

(the snippet from `examples/` dir)

### Actual Behavior

Two lines of introduction, two colons:

> ## Import
>
> Import is supported using the following syntax:
>
> The [`terraform import` command](https://developer.hashicorp.com/terraform/cli/commands/import) can be used, for example:
>
> ```shell
> terraform import wireguard_asymmetric_key.example "EFr5/97eoK32SeMingmUqJpE4TL21nckcl2jQ9ZT82g="
> ```

### Steps to Reproduce

1. `git clone --single-branch --branch=dependabot/go_modules/github.com/hashicorp/terraform-plugin-docs-0.24.0 https:/github.com/OJFord/terraform-provider-wireguard`
2. `cd terraform-provider-wireguard`
3. `tfplugindocs generate`
