[Feature Request] VitePress markdown support in vue-tsc

[skirtles-code]

Volar in VS Code already supports type checking VitePress markdown files via vue.server.vitePress.supportMdFile. I'd like to be able to run type checking for .md files from the command line using vue-tsc.

The use case is a pre-commit hook that I'm using to run type checks prior to every commit.

🤔 I guess you need to add markdown files into your tsconfig.json's include field

@so1ve I believe my configuration is all correct. It works fine in VS Code, but they're ignored by vue-tsc.

I originally asked this as a question in #3448 and Johnson suggested (not on that thread) that I should open a feature request for it.
