Update the pipe_consistency_linter() default to be '|>'?

[MichaelChirico]

The upstream style guide now unambiguously recommends |> over %>%:

https://style.tidyverse.org/pipes.html#magrittr

Therefore I think we should update our default in pipe_consistency_linter() from "be consistent" to "use |>".

[AshesITR]

Agreed. Though some syntax sugar for the magrittr pipe is lost and for older code bases I would hardly recommend refactoring to change the pipe style. The NEWS.md should include some guidance for this case I think.
