Bumps js-yaml from 4.1.1 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)

• Remove quadratic complexity from !!omap addItem. Regression from v5 (usually not critical, because YAML11_SCHEMA is not default anymore).

4.3.0, 3.15.0 - 2026-06-27

Security

• Backported maxTotalMergeKeys option.

• 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.
• Added dump() transform option for changing the generated AST before rendering.
• Added dump() options seqInlineFirst, flowBracketPadding, flowSkipCommaSpace, flowSkipColonSpace, quoteFlowKeys, quoteStyle and
