deps: body-parser@~1.20.4

[suuuuuuminnnnnn]

TL;DR

Updates body-parser from ~1.20.3 to ~1.20.4 to pull in patched qs@6.14.1 and clear the GHSA-6rw7-vpxm-498p advisory. Single-line change, full test pass, npm audit --production reports 0 vulnerabilities.

Context

Issue

• Issue: expressjs/express Update body-parser dependency in https://github.com/expressjs/express/tree/4.x/ to 1.20.4 #7016
• Title: "Update body-parser dependency in 4.x/ to 1.20.4"

Problem

Express 4.x depends on body-parser, which transitively depends on qs. qs < 6.14.1 is flagged by GHSA-6rw7-vpxm-498p (HIGH severity: arrayLimit bypass → potential DoS via memory exhaustion).
This is reported as vulnerable (not malicious).

Dependency chain (before)

express@4.22.1
└── body-parser@1.20.3
    └── qs@6.13.0 (vulnerable)

Additional context (#6972)

With ~1.20.3 in package.json:

• Fresh installs may resolve to newer patch releases, but
• Existing installations running npm install express@4 can remain on 1.20.3 since it still satisfies ~1.20.3.

Bumping the minimum to ~1.20.4 makes the safe patch-level update explicit.

---

Changes

• package.json: bump body-parser from ~1.20.3 → ~1.20.4 (single-line change)
• No lockfile changes (repo policy)

- "body-parser": "~1.20.3",
+ "body-parser": "~1.20.4",
