ggplot2 3.4.2

This is a hotfix release anticipating changes in r-devel, but folds in upkeep
changes and a few bug fixes as well.

Minor improvements

• Various type checks and their messages have been standardised
  (@teunbrand, #4834).

• ggplot2 now uses scales::DiscreteRange and scales::ContinuousRange, which
  are available to write scale extensions from scratch (@teunbrand, #2710).

• The layer_data(), layer_scales() and layer_grob() now have the default
  plot = last_plot() (@teunbrand, #5166).

• The datetime_scale() scale constructor is now exported for use in extension
  packages (@teunbrand, #4701).

Bug fixes

• update_geom_defaults() and update_stat_defaults() now return properly
  classed objects and have updated docs (@dkahle, #5146).

• For the purposes of checking required or non-missing aesthetics, character
  vectors are no longer considered non-finite (@teunbrand, @4284).

• annotation_logticks() skips drawing ticks when the scale range is non-finite
  instead of throwing an error (@teunbrand, #5229).

• Fixed spurious warnings when the weight was used in stat_bin_2d(),
  stat_boxplot(), stat_contour(), stat_bin_hex() and stat_quantile()
  (@teunbrand, #5216).

• To prevent changing the plotting order, stat_sf() is now computed per panel
  instead of per group (@teunbrand, #4340).

• Fixed bug in coord_sf() where graticule lines didn't obey
  panel.grid.major's linewidth setting (@teunbrand, #5179).

• geom_text() drops observations where angle = NA instead of throwing an
  error (@teunbrand, #2757).
