social-auth: auth against github issue

[ThomasWaldmann]

On February 6th, 2020 at 16:20 (UTC) your application (nsupdate.info) used an access token (with the User-Agent social-auth-3.2.0) as part of a query parameter to access an endpoint through the GitHub API:

https://api.github.com/user

Please use the Authorization HTTP header instead as using the access_token query parameter is deprecated.

Visit https://developer.github.com/changes/2019-11-05-deprecated-passwords-and-authorizations-api/#authenticating-using-query-parameters for more information.
