Describe the feature you want to add

There are multiple ways of authenticating OAuth 2.0 Clients at the /oauth2/token:

RFC 6749 section 2.3.1

• HTTP Basic Authorization (client_secret_basic) - the OAuth 2.0 Client ID and secret are sent in the HTTP Header (Authorization: basic ....)
• HTTP Body (client_secret_post) - the OAuth 2.0 Client ID and secret are sent in the POST body (Content-Type: application/x-www-form-urlencoded)

Currently, bruno only supports the client_secret_post method for client authentication. This feature request proposes adding support for client_secret_basic as configuration option.

Indeed this is a must-have feature to fully migrate the Oauth 2.0-supported API testing to Bruno
