proposed improvements to ggformula output from `mosaic::mplot()`

[nicholasjhorton]

Here's a sample output of mosaic::mplot() where I think that two improvements would be helpful:

1. move to base R pipe |> rather than magrittr pipe
2. suppress the geom_smooth() messages

gf_point(age ~ anysubstatus, data = HELPrct) %>%
  gf_smooth() %>% 
  gf_labs(title = "", caption = "")
`geom_smooth()` using method = 'loess'

I'm happy to move to |>, and was from the beginning. Perhaps we are far enough along now to do that systematically (all the examples in ggformula still have the old pipe).

I'll have to check if we can suppress the message by explicitly stating which method we want to use.

Note: The particular issue here is something to deal with in {mosaic}, not in {ggformula}.
