handoff: drop EACS#2 run-buildbot footnote (latest script was uploaded)

The footnote claimed SimpleMDM had a pre-touch version of the bootstrap
script during EACS#2; per Ryan, the latest script was in fact uploaded.
Dropping the inaccurate claim. The in-tree script
(`modules/macos_safaridriver/simplemdm-bootstrap-sip-safari.sh`) has
the `touch /var/tmp/semaphore/run-buildbot` baked into the driver
cleanup block (line 206), so the next EACS should bring the worker
online on its own.

-### ⚠️ One footnote on the 2nd round
-
-The bootstrap script that was uploaded to SimpleMDM at the time of
-EACS#2 was the version BEFORE I added `touch /var/tmp/semaphore/run-buildbot`
-into the driver cleanup block. So bootstrap finished clean, but the
-worker stayed dormant until I manually touched the file. **The
-current in-tree script
-(`modules/macos_safaridriver/simplemdm-bootstrap-sip-safari.sh`) HAS
-the touch baked in** — just make sure SimpleMDM is using the latest
-version, and the next EACS won't need any human follow-up.
