Patch Babel traverse vulnerability

[rockwellll]

Summary

• Force all transitive @babel/traverse dependencies to 7.23.2 through Yarn resolutions.
• Regenerate yarn.lock so the vulnerable 7.20.13 release is no longer installed.

Why

@babel/traverse 7.20.13 is affected by CVE-2023-45133, which can allow arbitrary code execution when Babel compiles malicious input through affected evaluation paths.

---

Note

Low Risk
Dependency-only security pin with no application source changes; main risk is minor Babel toolchain behavior differences between 7.20.x and 7.23.2 during builds/tests.

Overview
Pins every transitive @babel/traverse install to 7.23.2 via a new Yarn resolutions entry in package.json, replacing the vulnerable 7.20.13 tree.

yarn.lock is regenerated so the lockfile resolves @babel/traverse@7.23.2 (and the matching newer @babel/* packages that version pulls in) across all consumers.
