You need to use Tekton Pipelines v0.43.0 and onwards versions to get this working
Because once you refer an approval Task in the pipeline, then when it reaches approvalTask it creates a customRun and support for that is added in v0.43.0 https://github.com/tektoncd/pipeline/releases/tag/v0.43.0

And regarding Kubernetes version, it will work fine with 1.26 but if you want to use the cli then in that case you'll have to use k8s 1.28 and onwards
