- Muscle memory is a thing, as is relying heavily on one's shell
history. Now that the Jenkins runners are gone, `brew pull --bottle`
no longer works. This removes the option. If maintainers are confused,
they should [look at recent changes to the
docs](https://docs.brew.sh/Brew-Test-Bot-For-Core-Contributors#bottling),
or ask in Slack.
- An earlier iteration of this showed a deprecation warning and a link
to the docs, but when an option no longer physically works it's a bit
late for deprecation *warnings*.
- This also fixes a `brew style` warning from futher up in the file.
