Proposal: add "appid" query parameter

[infabo]

If the application has custom signing keys you can add a appid parameter to the openid-configuration-URL, so you receive the correct jwks_uri with the additional keys.

see https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-protocols-oidc

oauth2-azure/src/Provider/Azure.php

Line 69 in 3f8d322

$openIdConfigurationUri = $this->urlLogin . $tenant . $versionInfix . '/.well-known/openid-configuration';

It may be safe to add the appid-queryparam in all cases.
