gganimate 1.0.9

• Fix for using "svg" device during knitting (#484)
• Fix for correctly getting chunk options during knitting (#485)
• Fix a bug in transition_reveal() that would remove data during transitions
  (#480 and #473)
• General upkeep to keep it in line with the evolvling coding principles in
  ggplot2 (move to using vctrs, cli, lifecycle, etc)
• transition_reveal() now throws an error when it is used in conjunction with
  stat_align() and transitioning before the stat has been calculated (#476)
• Label interpolation now works when labels are expressions (#439)
• as_html_video() gains muted, loop, and controls argument to control
  presentation of the video. Like autoplay these can be controlled during knitr
  through the chunk options (e.g. gganimate = list(muted = TRUE, loop = TRUE))
  (#444)
• Make the build process up-to-date with ggplot2 3.5.0
