because the Travis-installed machine apparently has quite a few
Homebrew formulae installed, with an old version of Homebrew,
including a now-removed python@2, and that prevents updates of
python@3.

Remove the obsolete motivation for running (brew update), and replace it
with a similarly-good motivation that the Travis images are just too old
to be relevant to users.
