Fix for download failure when rest-client follows http redirect

[robinraju]

This PR tries to fix the issue described in #333

The following behaviour was observed when downloading files from a private repo.

• Github assets API started returning 302 and a location to the actual asset.
• The rest-client used in this action implicitly follows a redirect response along with the existing Authorization header.
• The url returned by GH API through the Location header contains a new token required for authenticating their assets API as a query param.
• It resulted in the following error

HttpError: <Error><Code>AccessDenied</Code><Message>Multiple auth mechanisms are not allowed; please use either query parameters or an Authorization header</Message>

Changes applied

Until a fix from typed-rest-client is available,

• I disabled allowRedirects option from the HTTP client and created a new request after removing the Authorization header to follow a redirect.
