Manifests out of date

[rkthtrifork]

Is your feature request related to a problem?/Why is this needed
The usage documentation suggests running the commands

kubectl kustomize https://github.com/kubernetes-csi/external-snapshotter/client/config/crd | kubectl create -f -

and

kubectl -n kube-system kustomize https://github.com/kubernetes-csi/external-snapshotter/deploy/kubernetes/snapshot-controller | kubectl create -f -

But the snapshot controller deployment manifest is not up-to-date. The version in the manifest is currently 8.2.1, but the newest image version is 8.3.0

Describe the solution you'd like in detail
I would like the manifests to always be up-to-date. I would suggest either a GitHub workflow for image releases which also bumps any necessary manifests or a makefile with a release target that both releases the new image and updates any necessary manifests.

Describe alternatives you've considered
The manifests are manually updated, but this is bound to be forgot at some point

Additional context
Nothing

#1325

There is a PR for helming this project. Once this PR is merged, this issue will be resolved. For each release, there will be separate static "snapshot-controller" manifest files with the appropriate image tag.
