[docusaurus-plugin-typedoc]: add the ability to add a separate frontmatter for readme file.

[aamir1995]

Readme is an essential part of the documentation, sometimes it serves as the main page for docs, I want to add a separate frontmatter for a readme file, such as hiding the title, toc, and navigation, currently there's no way to do this only for the readme file, the frontmatter property applies to all the generated files.

It would be great if we had a way of specifying a separate set of standard frontmatter only for the readme.
It could look something like this

readmeFrontmatter: {
 // standard docusasrus frontmatter here
}

Thanks!

ok sure. the next release will treat frontmatter slightly differently but I'll add details how to do this.
