Expose __path and __relativePath options on md instance for md plugins

[flingyp]

Is your feature request related to a problem? Please describe.

I found that #1240 has removed these two parameters, which makes it impossible for me to customize the MD plugin on this basis

Describe the solution you'd like

Can you __ Path and __ Relativepath these two attributes are added to the MD instance to better customize the MD plugin

Describe alternatives you've considered

They were not removed, they were moved to env.

FYI:

An env sandbox can be used alongside tokens to inject external variables for your parsers and renderers.

vitepress/src/node/markdown/env.ts

Lines 4 to 9 in 1e312f5

	export interface MarkdownEnv extends MarkdownItEnv {
	path: string
	relativePath: string
	cleanUrls: CleanUrlsMode
	links?: string[]
	}

Just noticed that MarkdownEnv type did not get exposed. See #1259

@meteorlxy I see __ data. Hoistedtags has also been deleted. If I need to add a script setup script code to the MD file to introduce my components. I should report to env.sfcBlocks.customBlocks insert script？

[meteorlxy]

env.sfcBlocks.scriptSetup would help.

See https://github.com/mdit-vue/mdit-vue/blob/main/packages/plugin-sfc/src/types.ts#L43-L76

@meteorlxy

I finally used env.sfcblocks.scripts because vitepress does not seem to handle 'env.sfcblocks.scriptsetup` code logic. But thank you for guiding me to solve the problem.

const vueSrc = [
    ...injectPageDataCode(
      sfcBlocks?.scripts.map((item) => item.content) ?? [],
      pageData,
      replaceRegex
    ),
    `<template><div>${replaceConstants(
      html,
      replaceRegex,
      vueTemplateBreaker
    )}</div></template>`,
    ...(sfcBlocks?.styles.map((item) => item.content) ?? []),
    ...(sfcBlocks?.customBlocks.map((item) => item.content) ?? [])
  ].join('\n')

[meteorlxy]

Uh yes, I forgot that.
