Render only index.adoc

[McPringle]

I have just created a repository for a documentation website. After some struggles everything is working now. But I have recognized that there is a HTML file for each adoc file. In my case I have an index.adoc which includes other adoc files (in the end there will be one file for each "chapter" of the documentation).

The action now searches for all adoc files and calls the asciidoctor command line with each file. So the result is one HTML file for each adoc file. In my case I only want to call asciidoctor with my index.adoc, because it includes all other adoc files to create a single page documentation while making maintenance easier with separate adoc files per chapter.

What do you think about it?
