Allow excluding styles for tags like h2 in vp-doc

[jd-solanki]

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

I am rendering components in .vp-doc and my component's h2 gets style of VitePress which I don't want.

Describe the solution you'd like

Add class not-vp-doc to omit applying styles

Describe alternatives you've considered

none

Additional context

I checked the source and found that all styles are written in CSS and it isn't quick to apply the :not() selector because there's list of vp-doc class usage and I might break something in hurry.

I am in hurry hence creating this issue instead of PR.

Will the team going to use SCSS in favor or refactor?

If you're in hurry, please use custom css with !important or something like that for a quick fix.
