refactor(tekton/v1): refactor ga release flow (#4092)

This pull request updates the Tekton pipeline for the GA release
process, mainly by replacing the `tag-rc2ga-on-oci-artifacts` task with
a new, more comprehensive `tag-and-deliver-rc2ga-on-oci-artifacts` task.
It also improves parameterization and error handling, and ensures that
registry information is consistently passed to relevant tasks.

Key changes include:

**Pipeline and Task Enhancements:**

* Replaced the old `tag-rc2ga-on-oci-artifacts` task with a new
`tag-and-deliver-rc2ga-on-oci-artifacts` task, which adds steps for both
tagging and delivering images and non-image artifacts, and introduces
support for publisher integration.
(`tekton/v1/pipelines/pingcap-release-ga.yaml`,
`tekton/v1/tasks/release/tag-and-delivery-rc2ga-on-oci-artifacts.yaml`,
`tekton/v1/tasks/release/tag-rc2ga-on-oci-artifacts.yaml`,
`tekton/v1/tasks/kustomization.yaml`)

* Added a new pipeline parameter `publisher-url` with a default value,
enabling dynamic configuration of the publisher service endpoint.
(`tekton/v1/pipelines/pingcap-release-ga.yaml`)

* Updated the pipeline to pass the `publisher-url` and `registry`
parameters to the relevant tasks, improving flexibility and consistency.

**Error Handling Improvements:**

* Changed error handling in `scripts/flow/rc/check-images-internal.ts`
to use `console.error` and `Deno.exit(1)` instead of throwing errors,
providing clearer CLI feedback and proper exit codes for CI/CD.
