List doesn't redirect

[anu-tiernan]

Describe the bug
When configuring the download hcl file to redirect certain packages it appears that it does not redirect list requests. Calls to fetch a specifi module version redirect fine however.

Error Message
N/A, no error message produced

To Reproduce
In this example I have a private go module repo which I wish to redirect to for packages under a certain prefix, the following config reproduces the issue, attempting to fetch @latest results in a 200 being returned for the list endpoint according to the logs. Fetching a specific version results in the expected 301 response.

mode = "none"
downloadURL = "https://australia-southeast1-go.pkg.dev/test-project/gopkg"

download "github.com/test-org/*" {
    mode = "redirect"
}

Expected behavior
All requests for redirected packages are redirected

Environment (please complete the following information):

• OS: Linux 64bit
• Go version : go1.22.2
• Proxy version : v0.14.0
• Storage (fs/mongodb/s3 etc.) : memory
