Add a script that fetches the current list of supported Pipeline LTS versions from tektoncd/pipeline's releases.md and writes them to .github/pipeline-lts.json. A weekly scheduled workflow runs this script and opens a PR if the versions have changed. The kind-e2e workflow now reads the LTS matrix from the JSON file using fromJSON() instead of a hardcoded list. This also picks up v1.12.0 which was previously missing.

The reusable e2e workflow now handles 'latest' as a pipelines-release value, using the latest/ URL path instead of previous/<version>/. This allows the k8s matrix job to always test against the latest Pipeline release without hardcoding a version. Signed-off-by: Vincent Demeester <vdemeest@redhat.com>

Pull request overview
This PR automates tracking Tekton Pipeline LTS versions used in Chains e2e runs by generating a version matrix from tektoncd/pipeline’s releases.md, and updates the reusable e2e workflow to support a latest pipelines release URL.
Changes:
- Add a script (
hack/update-pipeline-lts.sh) to extract active Pipeline LTS patch tags and write them to.github/pipeline-lts.json. - Add a scheduled workflow (
.github/workflows/update-pipeline-lts.yaml) to run the script weekly and open an automated PR when versions change. - Update e2e workflows to (a) consume the LTS list from JSON and (b) support
pipelines-release: latestin the reusable workflow URL.

Changes
Automate tracking of Pipeline LTS versions for e2e testing instead of
maintaining a hardcoded list that drifts out of date.
Commit 1: Automate Pipeline LTS version tracking
hack/update-pipeline-lts.sh: fetchesreleases.mdfromtektoncd/pipeline, extracts active LTS latest patch tags via awk,writes
.github/pipeline-lts.json.github/workflows/update-pipeline-lts.yaml: weekly cron +manual trigger, opens a PR when versions change
kind-e2e.yaml: read the LTS matrix from the JSON file usingfromJSON()instead of hardcoded versionsCommit 2: Support
latestin reusable e2e workflowlatestas apipelines-releasevalue, using the
latest/URL path instead ofprevious/<version>/latestinstead of a hardcoded versionThe goal is to eventually extract the script to
tektoncd/plumbingso allconsumer repos (cli, results, triggers, dashboard) can use the same mechanism.
