Brazil RP tests use a non-swagger compliant url

Apparently for the Brazil endpoints in the test we have things in this form:

https://www.certification.openid.net/test-mtls/a/ST1st/consents/v1/consents

but according to the swagger they should have 'open-banking' in the path:

https://www.certification.openid.net/test-mtls/a/ST1st/open-banking/consents/v1/consents

We should probably fix this, though no RP has raised it as an issue. (It would apply to all Brazil resource server endpoints, i.e. the resources endpoint too, and the payment consent / payment initiation ones.)
