Describe the bug

Hi,

I'm a new user, trying to add oathkeeper middleware to a gRPC service, but the application crashes during startup, before any explicit call to oathkeeper code.

As shown in the logs below, sql driver 'pgx' is being registered twice, once by the app and again by the middleware.

My application uses pgx v5, but one of oathkeeper's dependencies (x/watcherx) is loading v4, as shown by 'mod why':

github.com/ory/oathkeeper/middleware
github.com/ory/oathkeeper/driver/configuration
github.com/ory/x/watcherx
github.com/jackc/pgx/v4/stdlib

Any help would be appreciated.

Rodrigo
