[Feature request] Link check support

[Mister-Hope]

Clear and concise description of the problem

If we can add ability to check markdown links in devServer and warn users about broken link, we can improve user experience.

Suggested solution

Provide a link check option

Alternative

Use vuepress-plugin-md-enhance It supports this out-of-box

[meteorlxy]

Could be a plugin

[Mister-Hope]

vuepress-plugin-md-enhance already support this (and also GFM, so I would like your suggestions about converting it to an official plugin)

• open a PR to move it to @vuepress/markdown
• open a pR to create a new official plugin
• or remain this feature in my plugin

@meteorlxy Leave you point instead of leaving this issue here plz

[Mister-Hope]

An official plugin is released.
