Pull request overview
Adds a GitHub Actions workflow intended to automatically label issues closed by PRs merged into main with the next preview/RC label, inferred from existing release/* branches.
Changes:
- Introduces
.github/workflows/label-preview-version.ymlto compute the nextpreview-*/rc-*label based on branch names. - Queries closing issues for a merged PR via GraphQL and applies the computed label via the Issues API.
- Use pull_request_target instead of pull_request so fork PRs get a write token (the workflow doesn't execute PR code, only reads metadata) - Add pull-requests: read permission for the GraphQL query - Use Git refs API (listMatchingRefs) to fetch only release/ branches instead of listing all branches - Label all closingIssuesReferences without filtering by CLOSED state to avoid race conditions with GitHub's eventual consistency Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

When a PR is merged directly into a release branch (e.g. release/11.0-preview2), derive the label from the branch name (preview-2) instead of scanning for the next unreleased version. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
