Fix syntax errors in Colab environment patch

[ywchanna2001]

Fixed an extra quote in the pip uninstall command and a space in the os.getpid() call that prevented the NumPy downgrade from executing.

This fix is necessary because Google Colab's recent update to NumPy 2.0 breaks the existing AF-Cluster logic (specifically the use of np.NaN). Since the original patch cell had syntax errors, it was failing to downgrade NumPy, leaving the notebook in a broken state for all users.

Pull request overview

This PR updates the Colab notebook patch cell intended to work around a Google Colab / NumPy compatibility break by ensuring the downgrade commands execute correctly.

Changes:

• Fixes syntax/formatting issues in the NumPy downgrade cell (pip uninstall quoting and os.getpid() call).
• Updates the “Open in Colab” badge URL in the notebook header.
• Cleans some notebook metadata (e.g., execution_count set to null, removes cellView in one cell).

Comments suppressed due to low confidence (1)

• This cell’s metadata no longer includes "cellView": "form" while other parameterized/form cells in the notebook still do. If you want this “run first” patch cell to render consistently in Colab’s form view (and stay collapsed/organized), consider keeping the cellView metadata here as well.

      "metadata": {
        "colab": {
          "base_uri": "https://localhost:8080/"
        },
        "id": "3TEmlVAmCznf",

The “Open in Colab” badge now links to a fork/feature branch (ywchanna2001/.../fix-colab-numpy-bug). If this notebook is intended to be used from the upstream repo, the badge should point to the canonical repository/branch (typically HWaymentSteele/AF_Cluster on main) to avoid broken links once the branch is deleted or the fork diverges.
