packager: trying out @format

Summary: Internally when adding `format` we have a lint rule that automatically reformat using `prettier` and the project rule. I'm concerned how we can ensure this stays consistent when merging PRs though. It's not a big issue because the volume of PRs is low, but we'll have to figure it out later on.
