Summary

Fixes #7527

Adds the Location header to the CommonRequestHeadersList TypeScript type in both index.d.ts and index.d.cts. Based on the MDN Headers docs: https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers#redirects

Motivation

The Location header is a commonly used HTTP header (e.g., in redirect responses and certain request scenarios), but it was missing from the CommonRequestHeadersList union type. This meant that accessing or setting the Location header through Axios's typed header APIs did not benefit from type-safe autocompletion or validation.

Changes

• index.d.ts — Added "Location" to the CommonRequestHeadersList union type.
• index.d.cts — Added 'Location' to the CommonRequestHeadersList union type (CJS types).

Checklist

• Both .d.ts and .d.cts type files updated consistently
• No runtime behavior changes
• Backward compatible — existing code is unaffected

Summary by cubic
