ggsave error with type="cairo" or type="cairo-png"

ggsave produces an error when including  type="cairo" or type="cairo-png", which worked in ggplot2 <=3.3.3.
(R4.0.3, Windows 10)

```r
library(ggplot2)
p <- ggplot(mpg, aes(cty, hwy)) + geom_point()
ggsave("test.png", type = "cairo")
# also error for:
# ggsave("test.png", type = "cairo-png")
```
Error in png_dev(..., res = dpi, units = "in") :
  unused argument (type = "cairo")
