bpo-34370: Revert to using released Tk 8.6.8 with macOS installers

For 3.7.1rc1 and 3.6.7rc1 we used a pre-release development
snapshot of Tk 8.6 to pick up some post-8.6.8 fixes for macOS.
But the snapshot introduced at least one regression (bpo-34927).
For rc2, revert to using the standard release 8.6.8 for now.
This reverts commit adf493227f1efd5d6b34f46b854142bf3b5a411c.
