fix: error occurs when the link is purely numerical (#5479)

#### What type of PR is this?

/kind bug

/milestone 2.14.x

#### What this PR does / why we need it:

在默认的富文本编辑器中，使用了 [tiptap link](https://github.com/ueberdosis/tiptap/blob/b3ef574f3dd92852bc4dac24a82eb360db96c9c3/packages/extension-link/src/link.ts#L127C3-L135C5) ，而其中的 renderHTML 会对 href 进行处理，但当链接为纯数字的时候，`HTMLAttributes.href` 将不会有 `startsWith` 方法。

此 PR 将在解析 renderHTML 时，将 `HTMLAttributes.href` 转为 string，进而解决这个问题。

#### How to test it?

测试使用默认富文本编辑器时，编写一个链接，并将其设置为纯数字。
刷新页面，查看是否具有报错。
