ci: Add markdownlint, test_converting_readme, and build_docs workflows

Browse source 
* markdownlint runs against README.md to avoid any issues with
  converting it to HTML
* test_converting_readme converts README.md > HTML and uploads this test
  artifact to ensure that conversion works fine
* build_docs converts README.md > HTML and pushes the result to the
  docs branch to publish dosc to GitHub pages site
