Create new team with administrator access and add renovate-bot user to it

Renovate will scan each repo and look for renovate.json file.

Congfigure renovate

For kubernetes manifests files config looks quite simple.

{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "timezone": "Europe/Warsaw",
  "automerge": false,
  "dependencyDashboard": true,
  "kubernetes": {
    "managerFilePatterns": [
      "**/*.yml",
      "**/*.yaml"
    ]
  }
}

Renovate will create Dependency Dashboard issue in repo and will update its description when new release is found

After a while it will create pull request with latest image e.g https://codefloe.com/rpi-homelab/kubernetes-manifests/pulls/7
