Warning message: The `size` argument of `element_rect()` is deprecated as of ggplot2 3.4.0.

[XiangyunHuang]

following code will give a warning message now, because tidyverse/ggplot2#3672

library(likert)
data("MathAnxiety")
math_anxiety <- likert(summary = MathAnxiety)
plot(math_anxiety, type = "bar", legend.position = "bottom")

Warning message:
The size argument of element_rect() is deprecated as of ggplot2 3.4.0.
Please use the linewidth argument instead.

Would you mind updatingplot() code.
