New locale query parameter localizes OAuth Consent page

[matecsaj]

A new locale query parameter is now available for the GET https://auth.ebay.com/oauth2/authorize OAuth endpoint. This new query parameter will allow the developer/seller to localize the OAuth consent page based on the marketplace you're targeting. See the Configuring the HTTP query parameters section of the Getting user consent page for more information on this query parameter and using the GET https://auth.ebay.com/oauth2/authorize OAuth endpoint.
