Correct CHANGELOG to mention inset not inline (#19700)

I noticed this when reading the changelog to migrate a project to the
new version. I'm not sure whether retroactively changing the changelog
is considered acceptable behaviour in this project or whether appending
a notice in the next changelog would be better.

Funnily this was actually guessed in #19613, though hard to notice among
the other many false guesses.
