[dependabot]

Bumps js-yaml to 5.2.1 and updates ancestor dependency markdownlint-cli2. These dependencies need to be updated together.

Updates js-yaml from 4.1.0 to 5.2.1

Changelog

Sourced from js-yaml's changelog.

[5.2.1] - 2026-07-02

Fixed

• Add Map support to !!omap (should work when realMapTag used)

• Reworked JSON_SCHEMA and CORE_SCHEMA with spec-compliant scalar resolution rules, and added YAML11_SCHEMA.
• Added realMapTag for lossless mappings with non-string and complex keys. Object-based mappings now reject complex keys instead of stringifying them.
