Link the IGC issue from the scan-over-group workaround comment (#3145)

The PR updates the comment above the `atomic_fence` workaround in
`custom_inclusive_scan_over_group`
(`dpnp/tensor/libtensor/include/utils/sycl_utils.hpp`): it is shortened
and now links the IGC issue tracking the miscompile, so the workaround
can be removed once a fixed IGC is the minimum supported driver. No code
change.

The workaround is still required. Without it
`dpnp.tensor.cumulative_logsumexp` returns wrong results on Arrow Lake-S
and Panther Lake with the latest driver (compute-runtime 26.35.39758.10,
IGC 2.41.5), while it is correct with IGC 2.16.0 (compute-runtime
25.31.34666). The issue was reported to the IGC team with a standalone
SYCL reproducer.
