Enable Authorization: Bearer <token> in Swagger UI

[C-Duv]

It looks like the Swagger UI does not allow connecting to the API using a bearer token.

When I click the "Authorize" button, I am only offered to fill credentials for "OAuth2PasswordBearer (OAuth2, password)" security scheme. If enabled, the Bearer authentication HTTP authentication scheme one could use, on the Swagger UI, the token the README explain how to get.
