Use latest sycl bundle to build DPCTL

The intel/llvm/pull/10551 has been merged, so the build should succeed
and produce working binary.

The intel/llvm project has transitioned from sycl-nightly/YYYYMMDD tags to
nightly-YYYY-MM-DD tags instead.

The artifact of intel/llvm nightly build has also changed the name
and the structure. Adjusting the code for that.
