Brief description of your issue

WingetCreate new does not download a file even though you can download the file in Edge browser. File can be downloaded without authentication to the website.

Steps to reproduce

when using "WingetCreate new" with the url "https://httpbin.org/user-agent" returns no user-agent string.

This is what it returns.
{
"user-agent": ""
}

This causes downloads not to be downloaded because it is a standard practice to identify oneself to the internet server. Most sites interrogate and can present different content (or deny content) based upon the user-agent string. See https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/User-Agent

Example is Atlassian Jira download - https://www.atlassian.com/software/jira/downloads/binary/atlassian-jira-software-9.12.25-x64.exe

$url = "https://www.atlassian.com/software/jira/downloads/binary/atlassian-jira-software-9.12.25-x64.exe"

Invoke-WebRequest -Uri $url -OutFile New-TemporaryFile -Headers @{ "User-Agent" = $userAgent }
