Target path is not being set correctly when prepending path

[jonasolesen]

Environment

Package version 0.1.2
Node.js 18.16.0

Reproduction

I initially reproduced the error by using nitro and configuring the devProxy like so:

devProxy: {
  "/posts": {
    target: "https://jsonplaceholder.typicode.com/posts",
    changeOrigin: true,
    prependPath: true,
  },
},

It turned out to be a bug with httpxy instead, but I figured the reproduction would be obvious enough using the nitro playground with the above configuration rather than forking the repo.

Describe the bug

Using the provided configuration, I assume the expected behavior would be to proxy a request to the /posts path to https://jsonplaceholder.typicode.com/posts, but it seems to be forwarded to just https://jsonplaceholder.typicode.com instead. I (supposedly) fixed the bug by changing the property used when determining the target path from path to pathname as per the URL class API documentation. I'll submit a PR shortly.

Additional context

Another issue reporting the bug: unjs/nitro#1643
