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

Start with the turtle.dot documentation and reproduce turtle.dot(size="blue") on the CPython main branch, as described in the report. Trace the turtle.dot entry point to determine whether the implementation or documentation is inconsistent; done means the call's behavior matches the documented signature and invalid size usage is handled consistently.
