[SYCL][CUDA] fix NVVM wg size annotations typo (#21264)
Correct a typo in the NVVM annotation mapping for reqd_work_group_size.
During CUDA 13 testing, I noticed that the following tests fail because
of it:
- Basic/reqd_work_group_size.cpp
- Basic/work_group_size_prop.cpp
- Graph/Explicit/work_group_size_prop.cpp
- Graph/RecordReplay/work_group_size_prop.cpp
- Regression/no-split-reqd-wg-size.cpp
