Describe the bug / provide steps to reproduce it

If I configure the Packages field in my vale.ini with a URL, and the URL happens to be incorrect or inaccessible, Vale reports:

opening zip archive for reading: creating reader: zip: not a valid zip file

This is misleading. I spent a long time trying to diagnose that error and potential problems in the ZIP file when the problem was a lack of authorization to access the ZIP archive.

When a Package URL involves a non-existent domain, Vale does report:

Get "https://example.example/style.zip": dial tcp: lookup example.example: no such host

That's useful! 4xx or 5xx HTTP errors for package downloads should be reported as such instead of blaming the ZIP file.
