chore: update js-yaml to patched release

[jakehobbs]

Updates the root js-yaml dependency to ^4.2.0 and regenerates the lockfile so the repo-level TypeDoc YAML generator resolves to the patched release.
The lockfile diff has been narrowed back to js-yaml only; unrelated axios/tmp/yaml churn was removed.
Validation: pnpm install --lockfile-only, pnpm install --frozen-lockfile --ignore-scripts, and node -p "require('js-yaml/package.json').version".
Note: full pnpm audit still reports separate transitive Lerna/Nx js-yaml paths that require broader tooling changes.

Pull request overview

This pull request updates the workspace’s YAML parsing dependency to a patched js-yaml release and forces Lerna to resolve js-yaml to that patched version via a scoped pnpm override, aiming to secure usage in scripts/generate-typedoc-yaml.ts without a Lerna major bump or pnpm patches.

Changes:

• Bump root js-yaml devDependency from ^4.1.1 to ^4.2.0.
• Add pnpm.overrides["lerna>js-yaml"] = ^4.2.0 to ensure Lerna’s js-yaml resolution is patched.
• Update pnpm-lock.yaml to reflect the new override and resulting dependency graph changes.
