Basically implement my resolve file includes GH action as a built-in feature of nugetizer.

This would allow a package readme to simply reference other files within a repository, like:

<!-- include ../../readme.md#content -->
<!-- include ../../docs/footer.md -->

Where the main project readme could contain a bunch of project-level info, contrib, badges, etc., which you can skip by marking a specific area as the #content anchor:

# My Project
// bunch of badges
// building/contributing, etc.

<~-- #content -->
# Usage
// now the real stuff we want in a package readme

The footer.md could contain project sponsors and the like, and also be reused across multiple packages.
