Update devdocs for bounds checking following #18401

I had forgotten that this behavior was documented in the developer section of the manual when authoring #18401.

 The overall hierarchy is:

 Here ``A`` is the array, and ``I`` contains the "requested" indices.

 If you have to customize bounds checking for a specific array type,
 you should specialize ``checkbounds(Bool, A, I...)``. However, in most
