Need a prominent version number

```
In order to get this library updated on cdnjs, someone needs to submit a pull
request which follows the rules at https://github.com/cdnjs/cdnjs A very old
version of this library is already on cdnjs as 1.0, but I can't find a proper
version number for pagedown, so can't update that version number to the correct
value when supplying the latest source.

在專案的 package.json 或任何其他資訊清單檔案中尋找版本號。檢查儲存庫的標籤或發行版本，確認是否定義了版本。確認版本後，遵循 cdnjs 提交規則更新程式庫版本。在提交 pull request 之前，確保最新原始碼與版本號相符。
