Review comment:
This might not be the absolutely right way to do this: at this point we
will be using `group_vars.arrow_dplyr_query` which we do define, but R CMD
check isn't able to catch that.
`dplyr::group_vars` is simply `UseMethod("group_vars")` so this should just
work, but there might be a more approved solution for this case of referencing
an s3 method without importing it directly
