[ScrapCodes]

Changes

1. Migrate to customrun for the entire CEL codebase, including examples.
2. Update tekton version and related dependencies
3. Update the Readme to indicate that CEL has migrated
   v1beta1.CustomRuns and last commit that supports v1alpha1.Run.

Not sure can the custom task reconcile both v1alpha1 and v1beta1 for this migration? If not we might want to have the commit number in the readme for the ones who still want to run custom task in v1alpha1 api.

While testing I have found following case to be not working.

apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
  generateName: pipelinerun-
spec:
  pipelineSpec:
    params:
    - name: is-red-expr
      type: string
    tasks:
      - name: is-red
        taskRef:
          apiVersion: cel.tekton.dev/v1alpha1
          kind: CEL
        params:
          - name: is-red-expr
            value: “$(params.is-red-expr)"
  params:
    - name: is-red-expr
      value: "{'blue': 0x000080, 'red': 0xFF0000}['red'] == 0xFF0000"

Error:

Following example works:

apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
  generateName: pipelinerun-
spec:
  pipelineSpec:
    tasks:
      - name: get-blue
        taskRef:
          apiVersion: cel.tekton.dev/v1alpha1
          kind: CEL
        params:
          - name: blue
            value: "{'blue': 0x000080, 'red': 0xFF0000}['red'] == 0xFF0000"

Is this related to parameter substitution?

[ScrapCodes]

When "$(params.is-red-expr)" was replaced by $(params.is-red-expr), it started working.
