Remove playground executor workflow

[Copilot]

The playground executor workflow was removed as playground snapshot generation now relies on the Actions secrets PLAYGROUND_SNAPSHOTS_TOKEN and PLAYGROUND_SNAPSHOTS_REPO configured in the playground-snapshots-refresh workflow.

Changes

• Removed workflow files

  • .github/workflows/playground-executor.md
  • .github/workflows/playground-executor.lock.yml

• Updated documentation references

  • Removed playground executor entry from Labs page (docs/src/content/docs/labs.mdx)
  • Removed example comments in docs/scripts/fetch-playground-org-owned.mjs
  • Removed file references from docs deployment workflow (docs.yml)

Verification

The playground-snapshots-refresh workflow already uses the required secrets:

- name: Regenerate playground snapshots
  env:
    PLAYGROUND_SNAPSHOTS_TOKEN: ${{ secrets.PLAYGROUND_SNAPSHOTS_TOKEN }}
    PLAYGROUND_SNAPSHOTS_REPO: ${{ secrets.PLAYGROUND_SNAPSHOTS_REPO }}
    PLAYGROUND_SNAPSHOTS_MODE: actions

Original prompt

Remove playground executor and update Reflresh playground snapshots workflow to use repos Actions secret PLAYGROUND_SNAPSHOTS_TOKEN to get data from PLAYGROUND_SNAPSHOTS_REPO.
