`request` separated from `options` as params to `authenticateRequest`

There has been a change to the way the params of the authenticateRequest function are structured. The request param, formerly included in an options object, has been moved to stand on its own as the first param to the function, while the options object remains as the second param. Example below:

- clerkClient.authenticateRequest({ ...opts, request })
+ clerkClient.authenticateRequest(request, { ...opts })
