docs: fold phrase in Chinese into one line

[juzhiyuan]

Improved or typo fixed.

Hi,

In our Chinese Documentations, we have breaking lines in original markdowns, e.g

`Plugin` 配置可直接绑定在 `Route` 上，也可以被绑定在 `Service` 或 `Consumer`上。而对于同一
个插件的配置，只能有一份是有效的，配置选择优先级总是 `Consumer` > `Route` > `Service`。

在 `conf/config.yaml` 中，可以声明本地 APISIX 节点都支持哪些插件。这是个白名单机制，不在该
白名单的插件配置，都将会被自动忽略。这个特性可用于临时关闭或打开特定插件，应对突发情况非常有效。
如果你想在现有插件的基础上新增插件，注意需要拷贝 `conf/config-default.yaml` 的插件节点内容到 `conf/config.yaml` 的插件节点中。

And it's be rendered differently in different browsers, e.g

Chrome

Firfox

Here has one PR about this: #5823

Solution

After discussions in PR #5823, @Josh-Cena suggested we could use Prettier[1] to format our Chinese documentations with "proseWrap": "never" enabled, and it will collapse all wrapping line breaks. And also, Zexuan Luo suggested[2] we could add a CI to check this case 🥳

BTW, for the reason why it will have a different rendered effect, please see this comment[3].
