Support for geom_star

The {ggstar} package provides useful additional shapes in ggplots with the geom_star function. If support for this could be added within ggplotly, that would be very useful.

Minimal reprex:

mtcars %>%
  ggplot(aes(x=qsec, y=mpg)) +
  geom_point() +
  geom_star(data=mtcars[mtcars$mpg==max(mtcars$mpg),], #Add star at highest mpg value
            aes(x=qsec, y=mpg),
            color="black", fill="yellow", size=8, alpha=1)

从提供的最小 reprex 和 ggplotly 入口点开始，然后检查现有 ggplot2 几何对象的支持方式。完成标准是：ggstar 中的 geom_star 图层能够在生成的交互式图中正确渲染，包括其星形和映射的样式。
