[ci] convert data.rayci.yml matrix to array syntax

[andrew-anyscale]

Convert data9build-multipy, datalbuild-multipy, and the two matrix-setup "arrow v23" test labels from matrix to array syntax. The two array test steps use ($) against datalbuild-multipy since both sides now share the python array key. Every remaining plain depends_on to data9build-multipy or datalbuild-multipy is replaced with (python=3.10) or (python=3.12) based on the python version each consuming step pins. The core.rayci.yml dask and modin test steps — which reference datalbuild-multipy cross-file — are narrowed to (python=3.12) and (python=3.10) respectively. The non-array datan/datamongo/datatfxbsl/datatfds builds are unaffected

Code Review

This pull request updates the Buildkite configuration by transitioning from matrix to array definitions for multi-python builds in core.rayci.yml and data.rayci.yml. It also refines job dependencies by explicitly specifying the python version in the depends_on fields. I have no feedback to provide.
