Correct the reversed row and column terms in the two-dimensional matrix layout explanation. The additional rewrite and multiply API documentation changes have been removed after review.

Closes #2618.

Validation: checked that size([[0, 1, 2], [3, 4, 5]]) returns [2, 3]. git diff --check passed. Documentation only; the complete test suite was not rerun for this revision.

Thanks for another doc PR, I appreciate the attention you are giving to them.

I agree that the words row and column were reversed in the first paragraph you rewrote in this PR. But I am unclear why there are any changes besides swapping those words to correct them? Please describe the benefits of your other edits. Thanks.

The extra explanation was intended to connect the array representation to matrix multiplication, but it is unnecessary for correcting the reversed terms here. I have removed those additions and restored the original multiply documentation. The remaining change corrects row and column in the matrices guide (d7f02f5).

Since this change is now so tiny, I am not going to add a HISTORY entry for it, thanks for understanding (and thanks for finally addressing this). Merging.
