Explicit set of the API version used in conformance testing (#2350)

This PR proposes to define the API version used during testing
explicitly (and to set it to `2024.12`).
The tests relating to advanced indexing are failing now due to known
limitation in dpctl, so it is proposed to temporary disable them with a
proper comment.
