Background
I (@phuedx) have been writing "infobox" as in en:Template:Infobox. In the codebase, however, there are instances of InfoBox, infoBox, infobox, and accordion (see https://codesearch.wmcloud.org/extensions/?q=(%5BIi%5Dnfo%5BBb%5Dox%7Caccordion)&repos=Extension:IPInfo ).
AC
- Decide between "info box", infobox, or accordion
- Update the codebase accordingly
- Update mw:Extension:IPInfo accordingly
