Let's also remove:

• [x] Documentation of browndog functionality in book_source/
• [x] browndog handling steps in web/ (mostly but not all in php files)
• [x] web config files in docker/web/config/docker.php and base/utils/tests/testthat/data/config.example.php

And not edit:

• XML files in tests/ (I think this contradicts what I said when we talked live, but I'm now leaning toward not disturbing them)
• scripts in inst/ folders (I think just in the benchmark package, but same goes for inst in other packages)

@Sweetdevil144 It looks like your commit of the final dependency update got pushed to #3324 instead of here.

To fix, please:

git checkout delete-browndog
git pull # (assumes you have your local branch set up to track Sweetdevil144/delete-browndog; if not, replace this line with however you sync your local and remote branches)
git cherry-pick 0ac5b39d5
git push #(same assumption as above)

Don't worry about removing commit 0ac5b39d5 from #3324 -- we'll merge this PR first and it'll become a no-change there.
