Bump js-yaml and markdownlint-cli

[dependabot]

Bumps js-yaml to 4.3.2 and updates ancestor dependency markdownlint-cli. These dependencies need to be updated together.

Updates js-yaml from 4.1.1 to 4.3.2

Changelog

Sourced from js-yaml's changelog.

4.3.2 - 2026-08-26

Changed

• [backport] Hard-limit merge sequence size to 100.

Security

• [backport] Count empty mappings in merge sequences toward maxTotalMergeKeys to limit CPU usage, #797.

4.3.1 - 2026-07-31

Security

• [backport] Remove quadratic complexity from !!omap duplicate key detection.

4.3.0 - 2026-06-27

Added

• [backport] Added maxTotalMergeKeys (10000) loader option to limit the total number of keys processed by YAML merge (<<) across one load() / loadAll() call.

Fixed

• Restore umd builds back to es5.

Removed

• [backport] maxMergeSeqLength replaced with maxTotalMergeKeys for limiting YAML merge processing.

[4.2.0] - 2026-06-01

Added

• Added docs/safety.md with notes about processing untrusted YAML.
• Added maxDepth (100) loader option. Not a problem, but gives a better exception instead of RangeError on stack overflow.
• Added maxMergeSeqLength (20) loader option. Not a problem after merge fix, but an additional restriction for safety.
• Added sourcemaps to dist/ builds.

Changed

• Stop resolving numbers with underscores as numeric scalars, #627.
• Switched dev toolchains to Vite / neostandard.
• Updated demo.
• Reorganized tests.

Fixed

• Reject top-level block scalars without content indentation, #280.
• Ensure numbers survive round-trip, #737.

[dependabot]

Looks like these dependencies are updatable in another way, so this is no longer needed.
