Review label management

[simongdavies]

Two step process to remove ready-for-review label, allows for removing labels from a PR based on a fork.

Step 1 . Record the PR number that was updated (requires no write permissions) stores the PR number in an artefact tied to the workflow run.

Step 2. Runs when any Step 1 workflow completes, reads the PR number from the artefact and validates it, removes the Label from the PR if necessary

Pull request overview

This PR updates the “ready-for-review” label automation to a two-stage GitHub Actions pipeline so labels can be removed safely even when the triggering event originates from a fork (where the initial workflow only has a read-only token).

Changes:

• Replaces the previous single workflow with a Stage 1 “collect” workflow that records the PR number as an artifact on pull_request / pull_request_review events.
• Adds a Stage 2 “manage” workflow triggered by workflow_run that downloads and validates the artifact, then invokes the org reusable workflow to remove the label when appropriate.
• Updates label documentation to reference the new collect/manage workflow pair.
