Fix long code blocks

[kaelynj]

Some of the code blocks in our docs pages have lines which are too long and create a horizontal scroll bar across such as the one below:

This is a minor annoyance, but can be fixed pretty easily by shortening the length of the offending line. I'm not sure how many characters exactly creates a scroll bar, but we should have something reasonable.

To address this, we'll have to correct these by finding all the offending code blocks and fix them by hand.

Looks like we have a similar infra issue in #1806. Let's look into just making a CI check and automating this.
