handle redirects while trying to get console output

To double check:

• The right tests are in and the right validation has happened. Guidance: https://github.com/dotnet/arcade/blob/main/Documentation/Validation.md

I'm not sure if this is best fix @mmitche but at least this demonstrates the problem and outline one way how to fix it.

fixes #15598

Note that I was trying to use Client.SendAsync to send the retry. But that always adds 'Authorization` header and makes the request aways fail with 403 Authorization error. (that make sense since the token was originally for different host)

@dotnet/dnceng or @riarenas or someone versed on the Helix side should take a look at this.

PR Overview

This PR addresses an issue with handling redirects while retrieving console output by detecting a 302 status and sending a new GET request without the interfering Authorization header.

• Added a condition to check for an HTTP 302 status on the response.
• If a redirect is detected, a new HttpClient is instantiated to retrieve the stream from the provided Location header.
