Fix or suppress HTML warnings in Readme #144
Description
The auto-generated portions of the Readme, namely the contributors section, contains deprecated HTML elements. The resulting warnings were suppressed in a PR (#108), but since the HTML code is regenerated sometimes, we need a more permanent solution.
The first is, as was suggested by @favoyang here to disable HTML warnings for the whole Readme file.
Another is to find out if there is a way to configure the generated HTML code to not contain deprecated elements.
