Generate both v1beta1 and v1alpha2 api-docs

We automatically generate the api docs for the most recent verion of the
Gateway API. However, as the documentation refers to both v1beta1
resources, and some resources which have not yet graduted (eg TCPRoutes
etc) we have change the api-docs generation to include both.
