Improve html generation (#206)

* Update process_adoc_to_html.yml

add fetch-depth to make sure timestamps can be restored

* Renamed ReadMe.html -> index.html

* Use "indext.html" as output name

* update asciidoc html files [skip ci]

* bypass jeckyl

this ignores all files in _docs dir otherwise

* favicon should be relative

* FavIcon not resolved for all pages

* update asciidoc html files [skip ci]
