util._extend is deprecated

[pmcelhaney]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch http-proxy@1.18.1 for the project I'm working on.

Node 22 reports:

(node:37843) [DEP0060] DeprecationWarning: The util._extend API is deprecated. Please use Object.assign() instead.

Here is the diff that solved my problem:
