docs: improve doctests for ndarray instances in blas/ext/base/ndarray/dcusum*

Propagates fix from 638fdf0 ("docs: improve doctests for ndarray instances in `blas/ext/base/ndarray/gcusumkbn2`") to the five `dcusum*` sibling packages (dcusum, dcusumkbn, dcusumkbn2, dcusumors, dcusumpw), collapsing the two-step `{{alias}}(...);` + `{{alias:@stdlib/ndarray/to-array}}(y)` REPL doctest into the inline `<ndarray>[ ... ]` form.
