You don’t need to do it in initramfs any more.
cloud-init runs ‘growpart’ during the normal startup routine and it works fine on the newer kernels that can handle a running partition size change.
So just install ‘cloud-utils-growpart’ and either let cloud-init take care of it or run ‘growpart’ yourself.
