Setting of Authorization header in Get-WebFile cmdlet does not work

[gep13]

In the v0.11.0 version of Chocolatey, we attempted to ship a new piece of functionality (#1998) which would allow the setting of the Authorization header in the Get-WebFile cmdlet. This should have allowed downloading of files that are located behind a secure location, by passing in the necessary credentials to authenticate the request, however, it turns out that this change was not actually required. More details follow...

Unfortunately, a mistake was made where the wrong variable name was used when setting the header, and as a result, it was believed that this was why the setting of the Authroization header wasn't working, however, there was more to it than that!

When attempting to run set the Authorization Header in v0.11.1, you are met with the following error:

Even with the fix that was provided in this PR things still don't work.

This is due to the fact that the HttpWebRequest object in .Net doesn't actually have an Authorization property 😢

The fix that was merged into this v0.11.0 in this PR was invalid.

On further testing, the Authorization header, when set, was actually working as expected in v0.10.15, as per this comment. As such, the corrective action here will actually be to back out the change that was done in that PR, as it was actually working as expected.

The code that was used to valid this was the following, placed into a chocolateyInstall.ps1 file:

$options =
@{
  Headers = @{
    Accept = 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8';
    Cookie = 'requiredinfo=info';
    Referer = 'https://this-is-a-test';
   Authorization = 'super-secret-password';
  }
}

Install-ChocolateyPackage `
	-PackageName 'package' `
	-FileType 'msi' `
	-Url 'https://github.com/chocolatey/ChocolateyGUI/releases/download/0.19.0/ChocolateyGUI.msi' `
	-Options $options

Under the hood, Install-ChocolateyPackage calls Get-ChocolateyWebFile, which in turn calls Get-WebFile.
