The `util._extend` API is deprecated warning from `http-proxy` dependency in Node 22

[bayasdev]

Describe the bug

When running a Vite React TypeScript app I get the following deprecation warning:

(node:4364) [DEP0060] DeprecationWarning: The `util._extend` API is deprecated. Please use Object.assign() instead.

There's already PR that fixes this warning http-party/node-http-proxy#1666 but the http-proxy package seems to not be well maintained as its last release dates back from 2020.

I think a Vite side patch could be implemented like this one cap-js-community/odata-v2-adapter#46
