[Bug?]: Network error output should include status message (reason phrase)

Describe the bug

When a request fails, currently the output looks like this:

$ yarn install
➤ YN0000: · Yarn 4.9.2
➤ YN0000: ┌ Resolution step
➤ YN0000: └ Completed
➤ YN0000: ┌ Fetch step
➤ YN0035: │ unpopular-js@npm:1.0.12: The remote server failed to provide the requested resource
➤ YN0035: │   Response Code: 403 (Forbidden)
➤ YN0035: │   Request Method: GET
➤ YN0035: │   Request URL: https://repo.redacted.example.com/repository/npm-read-group/unpopular-js/-/unpopular-js-1.0.12.tgz
➤ YN0000: └ Completed in 6s 143ms
➤ YN0000: · Failed with errors in 6s 163ms

The status message / reason phrase would be really nice to also be output.

It appears there is intent to output the status message as prettyResponseCode method at

berry/packages/yarnpkg-core/sources/httpUtils.ts

Line 33 in dec0f9c

function prettyResponseCode({statusCode, statusMessage}: Response, configuration: Configuration) {

takes statusMessage as an input from the provided Response, but when that method is called at

berry/packages/yarnpkg-core/sources/httpUtils.ts

Line 64 in dec0f9c

value: formatUtils.tuple(formatUtils.Type.NO_HINT, prettyResponseCode(err.response, configuration)),

the statusMessage is not provided, which is why I'm calling this a bug (as the intent appears to be clear that the status message should be output but it is not actually output).

To reproduce

I have a proxy set up to block unpopular-js@1.0.12 for this test. Here's the package.json:

{
  "name": "@test/yarn-example",
  "version": "0.0.1",
  "description": "",
  "dependencies": {
    "react": "^19.0.0",
    "unpopular-js": "1.0.12"
  }
}

Environment

System:
    OS: Linux 6.15 Fedora Linux 42 (Workstation Edition)
    CPU: (12) x64 12th Gen Intel(R) Core(TM) i7-1255U
  Binaries:
    Node: 22.17.0 - /tmp/xfs-56ae242f/node
    Yarn: 4.9.2 - /tmp/xfs-56ae242f/yarn
    npm: 10.9.2 - /usr/bin/npm
    pnpm: 10.9.0 - /usr/bin/pnpm

Sorry for the false bug report - yarn berry actually does work correctly. My testing was flawed.
