WIP: Local ruby-advisory-db conventions

[jasnow]

Local advisory conventions that @postmodern and I (@jasnow) have used in the past and are not checked by "yamllint" or "rake" run.

5/12/2026

• The first step before submitting PRs is to run "yamllint" on the yaml files then run "rake". Both commands should find no issues. More info regarding yamllint HERE.
• See PR Changed 'indent-sequences:' from "consistent" to "true" in .ymllint.yml file. Fixed affected advisories. #1022 regarding checking for correct YAML field indentation.
• Field related:/url: is 4 blanks from left margin.
• Field patched_versions and unaffected_versions are 2 blanks from left margin.
• Postmodern likes:
  • Change "|-" to "|" on description: line.
  • Line wrap descriptions: and title: field at 80. (See CONTRIBUTING.md). @jasnow usually uses 75 because of the 2-char field indent.

5/13/2025

• Postmodern likes:
  • Not use "\n" in description: field.
  • No "POC" in description: field. They will be flagged during rake run and removed during harvesting.
• ruby yaml does not like embedded ":" characters.
