turtle.dot(size="blue") has a weird behaviour

Bug description:

The turtle.dot's documentation says:

turtle.dot()
turtle.dot(size)
turtle.dot(color, /)
turtle.dot(size, color, /)
turtle.dot(size, r, g, b, /)

    Parameters:

            size – an integer >= 1 (if given)

            color – a colorstring or a numeric color tuple

However, turtle.dot(size="blue") doesn't raise an exception. Instead of this, the color is changed to blue.

CPython versions tested on:

CPython main branch

Operating systems tested on:

Linux

从 turtle.dot 文档开始，并按照报告中的描述，在 CPython main 分支上重现 turtle.dot(size="blue")。跟踪 turtle.dot 的入口点，以确定实现或文档是否不一致；当该调用的行为与文档中记录的签名匹配，并且对无效 size 的使用得到一致处理时，即视为完成。
