GH-39533: [Python] NumPy 2.0 compat: remove usage of np.core (#39535)

### Rationale for this change Removing usage of `np.core`, as that is deprecated and will be removed in numpy 2.0. For this specific case, we can just hardcode the list of data types instead of using a numpy api (this list doesn't typically change). * Closes: #39533 Authored-by: Joris Van den Bossche <[email protected]> Signed-off-by: Joris Van den Bossche <[email protected]>
