chore: Bump js-yaml and markdownlint-cli2

[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 5.2.0 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)

Security

• 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.

CI failure on main — Run 30059417164

Failed job: Prettier (npm run format:check). Markdownlint, ESLint, and Tests all passed.

Root cause: 56 files fail Prettier's formatting check — all newly-added docs/2026/2026-R2/** content plus docs/2026/summaries/2026-R2.md, e.g.:

docs/2026/2026-R2/index.md
docs/2026/2026-R2/manifest.json
docs/2026/2026-R2/1-regional-updates/australia.md
docs/2026/2026-R2/accounts-payable/ap-automation-updates.md
... (56 files total)

These are the scraped/extracted 2026-R2 release notes that this PR brought in alongside the js-yaml/markdownlint-cli2 bump. They were apparently committed without running npm run format, so they don't match Prettier's expected style (list marker spacing, etc. — see the MD030 note in .markdownlint-cli2.jsonc about prettier/markdownlint conflicts).

Suggested fix:

npm run format        # runs `prettier --write` over the flagged files
git add -A
git commit -m "style: format 2026-R2 docs with prettier"

Then push and re-run CI. Since these are scraped content files (not hand-written), this is purely a formatting/whitespace fix — no content changes expected.
