Can't use `auth_patterns` with `--experimental_downloader_config`

### Description of the bug:

I have a downloader config that looks something like:
```
rewrite https://company.com:8443/(.*) https://company.com/$1
```
and a rule that looks like:
```
http_archive(
name = "archive",
url = "https://company.com:8443/archive.tar.gz",
auth_patterns = { "company.com": "Bearer " },
)
```

Only some networks need the `rewrite`, otherwise I would just change the URL. With this configuration, the `auth_patterns` are never used despite pointing to the same host.

### Which category does this issue belong to?

_No response_

### What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

You would need a remote archive that needs authentication, but I would think changing the url arbitrarily and using the downloader config would reproduce it.

### Which operating system are you running Bazel on?

macOS

### What is the output of `bazel info release`?

release 7.0.2

### If `bazel info release` returns `development version` or `(@non-git)`, tell us how you built Bazel.

Start by reproducing the interaction between --experimental_downloader_config, the rewrite rule, and http_archive's auth_patterns using the macOS Bazel 7.0.2 setup described in the issue. Confirm that rewriting the URL still applies the Bearer credential for company.com; done means an authenticated remote archive can be downloaded when the rewrite is active.
