Fix kroxylicious#1954: Generate asciidoc entrypoint file for kroxylicious-proxy book.

The way the release works right now, we need to generate a asciidoc entrypoint file.   As we've split out
kroxylicious-proxy into a separate book, we need this entrypoint point file to allow the plugin
to serve the content.
