Update YAML files to resolve yamllint-reported issues
The intent is that this should run on a pull request and be required to pass before the pull request can be merged.
Unlike the workflow in the GEDCOM and GEDCOM.io repositories, this workflow is configured to ignore trailing spaces since the generated YAML files have lots of trailing spaces (e.g., blank lines between paragraphs in the spec are converted to lines indented with four spaces) so the workflow would fail if not disabled.
