Support to promote the latest release to a particular environment

[LinuxSuRen]

Below is a regular kustomize YAML file:

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization

resources:
- manager.yaml

images:
- name: ghcr.io/kubesphere-sigs/ks-releaser
  newName: ghcr.io/kubesphere-sigs/ks-releaser
  newTag: v0.0.13

configMapGenerator:
- files:
  - controller_manager_config.yaml
  name: manager-config

I'd like to suggest having a feature to promote the latest release to a particular environment. Such as, if ks-releaser project just released v0.0.14, then create a PR to bump the version from v0.0.13 to v0.0.14.

Such as, we can have the following CRD:

kind: Promote
spec:
  releaser: xxx
  git: xxx
  environments:
  - name: int
     path: int
     policy: automated | pr
