cran_incoming() tweaks

[krlmlr]

• Add a show_archived = FALSE argument: typically, there are too many archived packages, when is this information useful?
• Sort by date by default

foghorn::cran_incoming() |> dplyr::count(cran_folder)
#> # A tibble: 7 × 2
#>   cran_folder     n
#>   <chr>       <int>
#> 1 archive       201
#> 2 inspect        13
#> 3 newbies        15
#> 4 pending         8
#> 5 pretest         7
#> 6 publish         2
#> 7 waiting        19
