+将字符串转换为小写的 URL “slug”。`slugify` 过滤器接受两个选项：
+
+1. `mode: string`。默认为`"default"`，它可选的值如下：
+   - `"none"`：没有字符
+   - `"raw"`：空格
+   - `"default"`：空格和非字母数字字符
+   - `"pretty"`：空格和非字母数字字符，但排除 `._~!$&'()+,;=@`
+   - `"ascii"`：空格、非字母数字和非 ASCII 字符
+   - `"latin"`：与默认相同，但拉丁字符首先进行音译（例如，àèïòü 转换为 aeiou）。
+2. `case: boolean`。默认为 `false`。如果为 `true`，则保留 `slug` 原本的大小写。
