Subject: [PATCH] Set the "nightly" branch to master HEAD every day

This GitHub Actions workflow runs every night at 8pm PDT / 9pm PST, and
sets the "nightly" branch to whatever master HEAD is at that time. The
TensorFlow team uses this branch for our suite of nightly tests, NOT for
the "tf-nightly" releases.
