fix: clear wording error in numpy warmup

[jbaremoney]

Description

In the backpropagation section, there was a comment saying the code was computing the gradient of parameters a, b, c, d wrt the loss. This is flipped and causes confusion about the math of backprop.

Specifically, the original comment:

“Backprop to compute gradients of a, b, c, d with respect to loss”

has been changed to:

“Backprop to compute gradient of the loss with respect to parameters a, b, c, d”
