ci: temporarily disable macOS build job (no runner available)

The Gitea instance currently has no macOS runner attached, so the
build-macos job was failing visibly on every release even with
continue-on-error: true, and the release body advertised macOS
downloads that were never produced.

- Gate build-macos with `if: false` (job is preserved verbatim
  except for the gate, so re-enablement is a one-line delete).
- Drop the macOS rows from the Downloads table generated by the
  create-release job. Kept as commented-out lines inside the heredoc.

Both changes carry a `TODO(macos-runner)` marker — `grep` for it
to find every site that needs flipping when a macOS runner is
connected.
