Container Service with v1beta1 API Not Generated

[j13tw]

Hi, we are testing this project to management GKE,
some feature of we wanted to use v1beta1 API on Container Server (GKE)
So we got the v1beta1 json file in project (https://github.com/Byron/google-apis-rs/tree/main/etc/api/container)
And we got the version of v1beta1/crates dir isn't update since the years of 2015
then we seems like not work after we run the make, make regen-api to gen dir
we just got the container1 and container1-cli
for another Service API State, we think needed to gen the container1_beta1 and container1_beta1-cli
Is there something Issue for generator the container service v1beta1 API ?
