DOC: adapt a docstest for numpy 2 (representation of scalars changed)

[neutrinoceros]

This is similar to https://github.com/astropy/astropy/pull/15065 Since there is no simple way to have these doctests pass with both versions of numpy, my understanding is that this should be merged after numpy 2.0.0 final comes out.

It's not user impacting, but it might still be helpful to convert to a Python float so the test pass with any NumPy. Let me know if it seems acceptable to you @mwcraig

This seems fine -- hopefully the next release of ccdproc (including the tests) can be compatible with both numpy 1.x mn numpy 2.x

Sure thing. Let me open a separate PR for that !

@mwcraig I just rebased this with the more portable change
