Run build on infinite scroll docs

Editor assessment

The chore type with an empty scope pair says the build is run on infinite scroll docs, with a pull request reference. The empty parentheses are a minor style wart, and the chore type fits a docs build tweak. The subject is imperative and unterminated, and no footer is needed. No body explains why the build was added, so the why is absent. Understandable and correctly typed but thin, it lands as acceptable.
