yamllint does not like it when you comment out pieces of dictionaries
in lists. Upcoming additions to the Dependabot configuration will run
afoul of this so we are updating the yamllint configuration.

Controlling the line length in the files generated from the Markdown to
YAML conversion would be difficult so we disable that yamllint rule.

Due to unexpected complications for user submissions we are reverting
the transition to a YAML format.

Add a GitHub Actions workflow and related files to automatically update
SOFTWARE-LIST.md when a push to the develop branch occurs. This
leverages the cisagov/md-table-to-yaml Python library to perform the
conversions.
